A 62.0 kg skier is moving at 6.10 m/s on a frictionless, horizontal, snow-covered plateau when she encounters a rough patch 4.50 m long. The coefficient of kinetic friction between this patch and her skis is 0.300. After crossing the rough patch and returning to friction-free snow, she skis down an icy, frictionless hill 2.50 m high. ▼ Part A How fast is the skier moving when she gets to the bottom of the hill?

You find yourself stuck in outerspace with nothing but your physics book and spacesuit. You have a mass of 108kg in your suit and your physics book has a mass of 3.7 kg. In order to make it back to your stationary spaceship before running out of air you must move at .29 m/s. How fast in m/s do you have to throw your physics book to achieve the speed
Dr. Jekyll (m = 70kg) is riding a skateboard when he realizes the cranberry juice he’s drinking is sweetened with artificial sweetener and turns into Mr. Hyde (m = 155kg). If Dr. Jekyll was initially moving at 6.5m/s, what is Mr. Hyde’s speed? (assume no external forces act)

Z Your answer is partially correct. Try again. In the figure here, two children are playing a game in which they try to hit a small box on the floor with a marble fired from a spring-loaded gun that is mounted on a table. The target box is horizontal distance D = 2.24 m from the edge of the table. Bobby compresses the spring 1.17 cm, but the center of the marble falls 29.0 cm short of the center of the box. How far should Rhoda compress the spring to score a direct hit? Assume that neither the spring nor the ball encounters friction in the gun.

Two bumper cars at the county fair are sliding toward one another (see figure below). Initially, bumper car 1 is traveling to the east at 5.62 m/s, and bumper car 2 is traveling 60.0° south of west at 10.00 m/s. After they collide, bumper car 1 is observed to be traveling to the west with a speed of 3.10 m/s. Friction is negligible between the cars and the ground. E Car 2 60 10.00 m/s Car 1 5.62 m/s (a) If the masses of bumper cars 1 and 2 are 600 kg and 631 kg respectively, what is the velocity of bumper car 2 immediately after the collision?

g Anderson Video - Work Done by a Spring A block of mass 0.2 kg is launched by a spring k₁= 2.0 N/m as shown below. The block moves along a frictionless horizontal table and pushes another spring, k₂= 2.3 N/m, to the maximum deflection z. If the initial deflection of the spring k, is 0.050 m, what is the maximum deflection of spring k₂? Consider that the masses of the springs are negligible.
