в. A x H HR

Ball A (m 0.5 kg, I 0.7 MR2) is held at rest against a spring, compressed by a distance x-40 cm. The ball is released and move along a frictionless surface (Ho 4 m) until it collides with ball B (m- 0.25 kg, I- 0.5 MR2) which is at rest. After the collision, the two balls roll down a track (which has friction!) and leaves the track at a height, H,- 1m. Ball B goes to a height of HB-5m before it comes to rest and ball A goes a height of HA-3 m before it stops. Find the spring constant, k, of the spring.

    A 2.1.0-kg block is accelerated from rest by a compressed spring (ks = 545 N/m). The block leaves the spring at the spring’s relaxed length. The block then travels along a rough horizontal with a coefficient of kinetic friction μk = 0.240 a distance of x = 6.90 m before frictional force stops the block. What was the original compression distance of the spring?

    A spring with spring constant 28 N/m is compressed a distance of 7.5 cm by a ball with a mass of 201.5 g (see figure below). The ball is then released and rolls without slipping along a horizontal surface, leaving the spring at point A. The process is repeated, using a block instead, with a mass identical to that of the ball. The block compresses the spring by 7.5 cm and is also released, leaving the spring at point A....

    Block A of mass, mA = 1.7 kg is shot from a spring device of spring constant, k = 700 N/m along a frictionless horizontal surface. The initial compression of the spring is 0.300 m. The shot makes the block rise to another horizontal level at a height h= 1m above the first. On this horizontal it collides with another stationary block B of mass mB = 3.5 kg. The blocks stick together and encounter a rough surface. The blocks...
