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.
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.
The answer depends on the direction (upward, horizontal, or downward) in which the ball leaves his foot.
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.
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.
just have oak leaves and sticks laid out horizontally sticks on the bottom and oak leaves above
Horizontal scrub

There necks are really long so they can reach the leaves at a high distance
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.
The velocity is greatest at two points:1). when it leaves the hand of the tosser2). when it returns to the same height as it was when it was releasedThis answer is the same for any angle above horizontal, regardless of the angle.
It's height allows it to reach the leaves of tall trees. They can only eat the leaves, so if they were not very tall, they would not be able to survive. Sent by henry. x
From the top of the radish to the tip of the leaves.
