1. A block of mass 3kg is place on top of a spring with a spring constant of 5000. If the spring is compressed by 0.5m and released from rest, how high does the block reach?

2. A 3kg ball is loaded in a spring-loaded cannon on top of a 100m cliff. The spring constant of the cannon is 5000. The spring is compressed by 0.5m and launched over the cliff at an angle of 30 degrees above the horizontal. What is the speed when the ball hits the ground?

A block of mass 0.630 kg is pushed against a horizontal spring of negligible mass until the spring is compressed a distance x. The force constant of the spring is 450 N/m. When it is released, the block travels along a frictionless, horizontal surface to point circled A, the bottom of a vertical circular track of radius R = 1.00 m, and continues to move up the track. The speed of the block at the bottom of the track is...

1) A block is released from point A and it slides down an incline (theta = 30 degrees) where the coefficient of kinetic friction is 0.3. It goes 5m and hits a spring with a spring constant k = 500 N/m. While it is being acted upon by the spring, assume it is on a frictionless surface. a) How far is the spring compressed? b) How far does the block go up the plane on the rebound from the spring?...

Question 1: A 2-kg wood block is pulled by a string across a rough horizontal floor. The string exerts a tension force of 30 N on the block at an angle of 20º above the horizontal. The block moves at constant speed. If the block is pulled for a distance of 3.0 m, how much work is done by the tension force?

A 100.0 g ball is launched from the top of a building. The ball is launched from rest by a constant force that is applied, resulting in the ball going from 0 m/s to 75 m/s over a distance of 60 cm. When the ball flies off the top of the building it has an initial velocity of 120.0 m/s @ 33.0o above the horizontal. Sitting on the ground is a tube, with a diameter slightly larger than the ball....

A student places a 1.200 kg block next to a spring of spring constant k=4960N/m. The system rests is on a frictionless horizontal surface (see figure). The horizontal surface at the top of a building. The distance from the horizontal surface to the ground below is 7.00m. The student pushes the block against the spring until it is compressed a distance 0.100m. The block is then released so that is slides off the edge of the building. Final answers must...

A 2.90 kg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0340 m . The spring has force constant 850 N/m . The coefficient of kinetic friction between the floor and the block is 0.42 . The block and spring are released from rest and the block slides along the floor. Part A What is the speed of the block when it has moved a distance of 0.0190 m from its initial position?...

A block of mass 200g is sitting on top of another block of three times that mass which is on a horizontal frictionless surface and is attached to a horizontal spring. The coefficient of static friction between the blocks is 0.2. The lower block is pulled until the attached spring is stretched by 5.0cm and is then released from rest. Find the maximum value of the spring constant for which the upper block does not slip on the lower block.

A block of mass m = 4.5 kg is attached to a spring with spring constant k = 610 N/m. It is initially at rest on an inclined plane that is at an angle of θ = 29° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.13. In the initial position, where the spring is compressed by a distance of d = 0.19 m, the mass is at...
