The best way is to take a cine film which takes images at fixed intervals. If you can then determine the distance moved between the images, you can calculate velocity.
you cannot. you need to know one or the other if you're doing a problem where someone is throwing something in the air, the final velocity is 0
find it and keep throwing ultra balls or just throw a master ball
To find the speed of the ball, you can use the formula for momentum: momentum = mass x velocity. Rearrange the formula to find the velocity: velocity = momentum / mass. In this case, velocity = 1300 kg / 15 kg ≈ 86.67 m/s.
Some channels show you the distance between the ball and the goal at freekicks. They also show the speed of the shot. On average a freekick is between 80 and 100km\h.
To calculate the velocity of the ball just before it hits the ground, we can use the equation of motion: velocity = acceleration x time. The acceleration due to gravity is approximately 9.8 m/s^2. Given the time of 3.0 seconds, we can plug these values into the equation to find the velocity. Therefore, the velocity of the ball just before it hits the ground is 29.4 m/s.
you are not born with the talent of throwing a baseball hard. all you have to do is work out a little bit.after that u practce throwing a baseball.try different ways of throwing it see wat fits u. watch baseball games and see how they throw after seeing them you might wanna try doing wat the do
I could not find any reliable data about middle school baseball pitchers being hit with baseballs. However, I'd guess that every ball player has been hit at least once.
You can use the principle of conservation of momentum. If the two balls have the same mass, the velocity of each ball after the collision can be calculated by taking the negative of the initial velocity of the single ball.
a) To find the initial speed, use the equation v = u - gt, where v is final velocity (0 m/s at the top of the trajectory), u is initial velocity (what we want to find), g is acceleration due to gravity (9.8 m/s^2), and t is time (3.0 s). b) To find the height reached, use the equation h = ut - 0.5gt^2, where h is the height, u is the initial velocity, g is acceleration due to gravity, and t is time. Sub in the values to get the height.
First, find an increment of distance. In between one place and another. Then, time how long it takes for the ball to get from point a to point b.Velocity= Distance divided by Time
Using the kinematic equation for projectile motion, the time the soccer ball is in the air can be found using the equation: time = (2 * initial velocity * sin(angle)) / acceleration. Substituting the given values, we find that the time the soccer ball is in the air is approximately 2.42 seconds.
The final velocity can be calculated using the formula final velocity = initial velocity + (acceleration * time). Since the ball starts at rest, the initial velocity is 0. The final velocity = 0 + (acceleration * 5). To find the acceleration, you can use the formula acceleration = (final velocity - initial velocity) / time. The final velocity is unknown, but we just calculated the final velocity is equal to 5 times the acceleration, so acceleration = (final velocity - 0) / 5. Substituting the final velocity = 5 times the acceleration into the acceleration equation, we get acceleration = (5 * acceleration - 0)/5. Solving for acceleration, we get acceleration = 1 m/s^2. The final velocity is 5 m/s.
