07.1

A 2.00kg mass is initially at rest on the end of a spring that is compressed by 40.0cm from its equilibrium position. The spring has spring constant 800 N/m. This mass is released and the

mass shoots away from the spring on a frictionless, horizontal surface. It then hits a 3.00kg mass, and the two masses stick together and slide up a rough-surface hill (with friction) on the other side to a vertical height of 30.0cm.

(a) What was the speed of the two masses right after their collision?

(b) How much energy was lost during the collision, and much how energy was lost to friction?

Box 1 of mass 2 kg is pressed against a spring with spring constant 600 N/m that is initially compressed by 0.5 m. The spring launches box 1 which then slides along a frictionless surface until it collides with box 2 (initially at rest) with mass 3 kg. They stick together, slide over a patch of sticky spilled soda with coefficient of kinetic friction 0.6 and length 1.2 m. Then, they fall off a cliff of height 3 m. How...

A block of mass 0.25 kg is against a spring compressed at 0.20 m with spring constant 50 N/m. When the spring is released, the block moves along the frictionless surface until entering a region with the coefficient of kinetic friction equal to 0.30 (when the block enters the friction region it is no longer in contact with the spring ). How far,L,into the region with friction does the block slide before stopping?

A 5.0 kg box slides down a 5.0 m high frictionless hill, starting from rest, across a 2.0 m wide horizontal surface, then hits a horizontal spring with spring constant 500 N/m. The ground under the spring is frictionless, but the 2.0 m wide horizontal surface is rough with a coefficient of kinetic friction of 0.25. a. What is the speed of the box just before reaching the rough surface? b. What is the speed of the box just before...

A mass m starts at rest at point A with the spring (spring constant k) compressed by a distance x. Mass m strikes and sticks to the mass M, and they slide together across a rough surface that provides a friction force f. Find out how far they slide from the original position of M before stopping. Provide the strategy analysis of this problem but do not solve the problem! Identify which physical principles need to apply to obtain a...

A block with mass m = 14 kg rests on a frictionless table and is accelerated by a spring with spring constant k = 4399 N/m after being compressed a distance x1 = 0.468 m from the spring’s unstretched length. The floor is frictionless except for a rough patch a distance d = 2 m long. For this rough path, the coefficient of friction is μk = 0.48. 1)How much work is done by the spring as it accelerates the...

A spring is mounted horizontally as shown to the right. A crate, which has a mass of 8.5 kg is pressed against the spring with a force of 350 N. As a result the spring is compressed a distance of 82.0 cm. The mass is then released and is allowed to slide along the horizontal, frictionless surface. a. What is the spring constant of this spring? b. How much elastic potential energy will be stored in the spring? c. How...

A 15-gram stone is shot horizontally at a 3.0 kg wooden block hooked to a relax 250 N/m spring (the other end of the spring is fixed against a wall, the spring at the block sitting on a horizontal frictionless table). It is observed that the stone bounces back with a speed of 10 m/s, and that the blcok compresses the spring by 4.0 cm. 1a. What was the speed of the stone just before collision? 1b. Calculate the energy...

A blue block has a mass of 0.92 kg and is stationary on a horizontal frictionless surface. It is struck with a rubber mallet causing it to slide with a speed of 3.1 m/s on the horizontal surface. The mallet is in contact with the block for 23 milliseconds. The blue block collides with a red block with a mass of 0.75 kg and the two blocks stick together. The two blocks slide up a long smooth incline and come...
