A person is riding on a flatcar traveling at a constant speed of 200 km/s (Fig.). He wishes to throw a ball through a stationary hoop 90 km above the height of his hands in such a manner that the ball will move horizontally as it passes through the hoop. He throws the ball with a speed of 250 m/s with respect to himself. (a) How many times required after he releases the ball will it pass through the hoop? (b) What must the vertical component of the initial velocity of the ball? (c) At what horizontal distance in front of the hoop must he release the ball? (d) When the ball leaves the man's hands, what is the direction of its velocity relative to the frame of reference of the flatcar? Relative to the frame of reference of an observer standing on the ground? 90 Km v = 200 km/s

A bullet travelig horizontally at a speed of 350m/s hits a board perpendicular to its surface, passes through and emerges on the other side at a speed of 210 m/s. If the board is 4.00cm thick, how long does the bullet take to pass through it.
In a high-speed police chase, a police van is racing after an assassin at a speed of 90 kmph. The assassin, however, is speeding off in a powerful sports car at 220 kmph in the same direction. The officer in desperation fires a bullet with a muzzle speed of 150 m/s at the assassin’s car. Calculate the speed when it hits the assassin’s car (assuming the officer does not miss)?
In 2004 two Martian probes successfully landed on the Red Planet. The final phase of the landing involved bouncing the probes until they came to rest (they were surrounded by protective inflated “balloons”). During one of the bounces, the telemetry (electronic data sent back to Earth) indicated that the probe too off at 25.0 m/s at an angle of 20 degrees and landed 110 m away (and then bounced again). Assuming the landing region was level, determine the acceleration due to gravity near the Martian surface.
A hunter aims directly at a target (on the same level as the gun) 75m away. If the bullet leaves the gun at a speed of 180m/s, by how much will it miss the target?
A carnival game has you throw a ball through a hoop as the hoop falls from some height. Suppose for onesuch game the hoop falls from a height of 2.0 m above your hand when you throw the ball, and you stand ahorizontal distance of 3.0 m away. If you throw the ball right when the hoop is released (from rest), at whatangle must you throw the ball in order for you to win the prize?
A ball rolls 10.0m [S] in a time of 6.00 seconds, hits a wall, and rolls back 21a distance of 15.0m [N] in a time of 10 seconds. Determine the average speed of the ball. Question: When solving for speed, would the time be 16 seconds or 10-6= 4 seconds? And why?
A rifle is aimed horizontally at the center of a large target 59 m away. If the distance from the center of the target to the point where the bullet strikes the target is 2.03 cm, calculate the initial speed of the bullet in m/s?
a quarterback throws a ball with a velocity of 50ft/s at an angle 40 above the horizontal towards an open receiver who is 30yd away. The pass is released 5.0 ft above the ground. Assume the receiver is stationary and will catch the ball if it reaches him. Will it be a complete pass? If not will it fall short or ''fly'' to the receiver?
