A tennis player wins a match at Arthur Ashe stadium and hits a ball into the stands at 30 m/s and at an angle . above the horizontal (). On its way down, the ball is caught by a spectator 10 m above the point where the ball was hit. (a) Calculate the time it takes the tennis ball to reach the spectator A ball rolls across a floor with an acceleration of 0.100 m/s^2 in a direction opposite to its velocity. The ball has a velocity of 4.00 m/s after rolling a distance 6.00 m across the floor. What.. The billiard ball that has an initial velocity of 15 m/s2 happened to stop after 3 seconds. To get its deceleration, we must divide the velocity by the time so it will be 15 meters per second squared divided by 3 seconds. The answer will be 5 m/s. This means that the billiard ball is moving 5 meters per second until its movement stopped

Here, I will shoot two balls straight up. In one case, I will measure the max height in order to find the launch speed (initial velocity). In the other cas.. So any projectile that has an initial vertical velocity of 14.3 m/s and lands 20.0 m below its starting altitude will spend 3.96 s in the air. a tennis player hits the ball at a height of 2.5 m and an from the basket, which is 3.05 m (10 ft) above the floor. A player standing on the free throw line throws the ball with an initial speed. When serving a tennis ball, a player hits the ball when its velocity is zero (at the highest point of a vertical toss). The racquet exerts a force of 540 N on the ball for 5.00 ms, giving it a final velocity of 45.0 m/s. Using these data, find the mass of the ball. A punter drops a ball from rest vertically 1 meter down onto his foot 30 m/s. A quarterback throws a pass at an angle of 35° above the horizontal with an initial speed of 25 m/s.

A projectile is fired horizontally with an initial speed of 57 m/s Suppose you lob the ball with an initial speed of 15 m/s an an angle of 50 degrees above the horizontal. At that instant your opponent is 10 m away from the ball. He begins to move away at 0.3 s later, hoping to reach the ball and hit it back at the moment that it is 2.1 m above its launch point

The velocity range was 14 m/s to 30 m/s and the spin range was -2400 rpm (backspin) to 2500 rpm (topspin); the range of C D was 0.453 to 0.567.

The lob in tennis is an effective tactic when your opponent is near the net. It consists of lofting the ball over his head, forcing him to move quickly away from the net (see the drawing).

The position of the ball relative to our body changes which parts of the ball we can make contact with. As a simple example, when we toss the ball in front of us on a serve we cannot make contact with the side of the ball closest to the net. The toss location (and the desire to hit it towards the net) preclude that The balls were launched from a table tennis ball machine that controls the spin and velocity of the ball using three rotors (Ozaki et al., 2013). By modulating the spin rate of the rotors, five different sets of velocity conditions were designed, ranging from 15 to 115 km/h. For all velocity conditions, back-spin was applied to the balls Forehand groundstroke effectiveness is important for tennis success. Ball topspin angular velocity (TAV) and accuracy are important for forehand groundstroke effectiveness, and have been extensively studied, previously; despite previous, quality studies, it was unclear whether certain racquet kinematics relate to ball TAV and shot accuracy during the forehand groundstroke Projectile Problems AP Physics 1 Use separate sheet/notebook to solve problems.
