Assume the ball's horizontal speed remains constant, since the only significant force is gravity which acts in the vertical direction. We can calculate the time of flight: time = distance / speed = 19.6m / 28ms-1 = 0.7s Consider now the vertical direction: we know that the ball took 0.7s to fall to the ground, and also that its initial vertical speed was zero. Its acceleration was g = 9.81ms-2. It is thus possible to deduce the vertical distance that it fell. s = ut + at2/2 ... but u = 0 = at2/2 = 9.81 x 0.72 / 2 = 2.40m to 3 significant figures.

A bullet fired horizontally from a rifle begins to fall?
As soon as it leaves the muzzle of the rifle. To hit a target at any distance, the line of sight of the barrel will be tilted so that it is ABOVE horizontal- and gravity will cause the bullet to curve back to earth- or your target.
If the ball leaves his foot from a height of 4 ft write an equation for the vertical height s (in ft) of the ball t seconds after being kicked?
The answer depends on the direction (upward, horizontal, or downward) in which the ball leaves his foot.
A train leaves danville junction and travels north at the speed of 75mph tow hours later a second train leaves on a parallel track and travels north at 125 mph how far from the station will they meet?
Plot distance vertical axis and time on horizontal and draw a graph with the first train leaving at zero time plot distance travelled in 4 hours I.E. 300miles draw a line. For second train start from 2 hours on time line and plot distance travelled in 4 hours I.E. 500 and draw line where they intercept draw a line to distance scale horizontally answer 375miles from the station.
When a rifle is fired horizontally the bullet leaves the barrel and doesnt drop at all for the first 35 meters of flight Is this true?
No, this statement is not true. When a rifle is fired horizontally, the bullet immediately begins to drop due to gravity as soon as it leaves the barrel. The rate of drop will depend on the muzzle velocity of the bullet and the distance it has traveled.
A bullet is fired horizontally out of a gun at the same time another is dropped from the end of the barrelthe one to hit the ground first is?
The bullet fired horizontally will hit the ground first, given that it has an initial horizontal velocity that keeps it moving forward from the moment it leaves the gun. On the other hand, the bullet dropped from the end of the barrel only has the force of gravity acting on it, causing it to fall vertically, which is slower than the horizontal motion of the fired bullet.
A long jumper leaves the ground at an angle 20 to horizontal and at speed of 11ms.how far does he jump and what the maximum height reached?
Making the improbable assumption that the jumper experiences no air resistance, he will jump 3.97 metres, and reach a height of 0.72 metres.
A shotputter throws the shot with an initial speed of 15.5 ms at a 34.0 angle to the horizontal calculate the horizontal distance traveled by the shot if it leaves the athletes hand at a height of 2?
To find the horizontal distance traveled by the shot, you can use the horizontal component of the initial velocity. The horizontal velocity can be calculated as v_horizontal = v_initial * cos(theta), where v_initial is the initial speed (15.5 m/s) and theta is the angle (34 degrees). After calculating the horizontal velocity, you can use it in the formula for horizontal distance: distance = horizontal velocity * time, where time can be calculated using the vertical component of the initial velocity to determine the time it takes for the shot to reach the ground.
How do you make grass traps on survival craft?
just have oak leaves and sticks laid out horizontally sticks on the bottom and oak leaves above
Large Tasmanian shrub with dense leaves and foliage?
Horizontal scrub
How do giraffes get leaves from a high distance?
There necks are really long so they can reach the leaves at a high distance
How do leaves grow on a eucalyptus tree?
The leaves of eucalyptus trees, or gum trees, grow hanging down, rather than horizontally. This is a special adaptation which minimises evaporation and hence water loss (transpiration), as the leaves are not as exposed to sunlight. The leaves usually have equal numbers of stoma on each side, unlike trees which hold their leaves horizontally - they tend to have all or most of their stoma on the lower side. The leaves also tend to have a thick, waxy coating which also minimises water loss.
What is an underground stem from which new leaves and roots can grow?
A rhizome is an underground stem that can produce new leaves and roots. It grows horizontally underground and can send out shoots and roots at various points. Examples of plants with rhizomes include ginger, bamboo, and iris.
