A tennis ball has a mass of 0.055 kg. A professional tennis player hits the ball hard enough to give it a speed of 52 m/s (about 117 milesper hour.) The ball moves toward the left, hits a wall and bounces straight back to the right with almost the same speed (52 m/s). Asindicated in the diagram below, high-speed photography shows that the ball is crushed about d = 2.4 cm at the instant when its speed ismomentarily zero, before rebounding.DMaking the very rough approximation that the large force that the wall exerts on the ball is approximately constant during contact,determine the approximate magnitude of this force.

A bullet of mass m = 8.00 g is fired into a block of mass M = 220 g that is initially at rest at the edge of a table of height h = 1.00 m (see figure below). The bullet remains in the block, and after the impact the block lands d = 1.60 m from the bottom of the table. Determine the initial speed of the bullet. __ m/s
Kyle, a 95.0 kg football player, leaps straight up into the air (with no horizontal velocity) to catch a pass. He catches the 0.430 kg ball precisely at the peak of his jump, when he is 0.538 meters off the ground. He hits the ground 0.0333 metersaway from where he leapt. If the ball was moving horizontally when it was caught, how fast was the ball traveling? ball's speed: ? m/s
A truck (M = 2500kg) collides with a car (m = 1000kg) at a 4-way intersection. Fortunately nobody gets hurt. Suppose the car is going north at 20m/s ( about 45mph) and the truck is coming from the east at 10m/s ( about 22mph). The car and truck stick together after the %3D collision. (a) Find the speed and direction of the car and truck immediately after the collision. (b) Approximately how much energy went into the deformation of the metal that caused the two vehicles to stick together? (c) What assumptions did you make? The
Two ice skaters stand together as illustrated in Figure (a) below. They "push off" and travel directly away from each other, the boy with a velocity of v = 0.720 m/s to the left. If the boy weighs 733 N and the girl weighs 486 N, what is the girl's velocity (in m/s) after they push off? (Consider the ice to be frictionless.) ν ?
