It's initial speed is 35.8 m/s directed at an angle 28 degrees above the horizontal. After 0.19 seconds what is the horizontal component of the balls velocity in m/s?A hockey puck is hit by a stick and slides off at an initial speed of 0.5 m/s. Assuming that the ice is frictionless, what is the speed of the puck after 1s?
- A ball is dropped from a height 30 m above the ground at t=0.0. Each time it bounces from the ground, its rebound speed is 60% of its impact speed. At the instant the first ball hits the ground, a second ball is released from the same place. Take g = 9.8 m/s2. At what height above the ground will they collide? (Take the ground as y=0.0 m)a)If Olaf catches the ball, with what speed vf do Olaf and the ball move afterward? Express your answer numerically in meters per second. b) If the ball hits Olaf and bounces off his chest horizontally at 8.30 m/sm/s in the opposite direction, what is his speed vf after the collision? Express your answer numerically in meters per second.1. A ball having 500.0 g hits wall with velocity 10.0 m/s. Wall applies to the ball and it turns back with velocity 8.0 m/s. Find the 5000.0 N for time of ball-wall contact. 2. A projectile is launched at 40° to the horizonal with initial speed 15 m/s. Determine the maximum height reached. (assume g = 9.81 m/s²)
- An archer shoots an 18.0-gram arrow at a 43.0-gram target on a wall 32.0 m high. If the arrow is shot at a velocity of v0 = 60.0 m/s, the speed of the arrow is 54.5 m/s when it reaches the target. If the arrow becomes embedded in the target and they both fly off the wall together, at what speed will they leave the wall? Should I use 60.0 m/s in the equation or 54.5 m/s: V’=(0.018)(60.0m/s)/ (0.061) -or- V’=(0.018)(54.5m/s)/ (0.061)The roof of a tall building is 25 m above the ground.

- A tennis ball of mass 57.0 g is held just above a basketball of mass 607 g. With their centers vertically aligned, both balls are released from rest at the same time, to fall through a distance of 1.40 m An illustration shows a tennis ball placed on top of a basketball with a downward-pointing arrow shown to the side. (a) Find the magnitude of the downward velocity with which the basketball reaches the ground. m/s(b) Assume that an elastic collision with the ground instantaneously reverses the velocity of the basketball while the tennis ball is still moving down. Next, the two balls meet in an elastic collision. To what height does the tennis ball rebound? mThe child in the figure throws the ball in his hand horizontally with smv/4.21=speed. The ball hits the ground with a collision coefficient of 8.0 = e and rises to a height h. Find the velocity of the ball when it first hits the ground, and then the greatest height h it will rise.In a baseball game, one of the players graps the ball and lessens the influence of the ball by moving his hand back. The ball touches the player's hand at a speed of 140.4 km/h in the horizontal direction. The ball is 152 gr. The player moves his hand back with an average speed of 8 m/s over 14 cm in the horizontal direction. In this way, the player has caused the ball to stop. Calculate the average impulsive force applied on the hand of the player.
