You have been asked to design a "ballistic spring system" to measure the speed of bullets. A spring whose spring constant is k is suspended from the ceiling. A block of mass M hangs from the spring. A bullet of mass m is fired vertically upward into the bottom of the block and stops in the block. The spring's maximum compression d is measured. Find an expression for the bulletť's speed vg in terms of m, M, k, and d. What was the speed of a 10 g bullet if the block's mass is 2.0 kg and if the spring, with k = 50 N/m, was compressed by 45 cm?

In the figure, block number 1 has a mass of 2 kg and block number 2 has a mass of 5 kg. The surface is frictionless and the spring constant k = 1120 N / m ‘. Objects move to the right at the speeds given in the figure. When the collision occurs after a while, the compression in the spring becomes maximum when the blocks have the same speed. What is the maximum compression of the spring?
Ball A, with a mass of 2kg, is thrown at a speed of 4 m/s to a suspended ball of 20kg mass, which is standing still. If the coefficient of return between the ball and the block is e=0.8, what is the maximum height H when the block momentarily stops during the collision?
Block A (with mass 10 kg) slides along a frictionless floor with a speed of 0.75 m/s and collides with Block B (with mass 12 kg) which was at rest and is attached to a spring with spring constant 24 N/m. The blocks stick together after the collision; what is the maximum compression of the spring?
A 31.0-kg skateboarder rides on a 10.0-kg skateboard at 5.7 m/s on a level road before jumping into air with a speed of 10.0 m/s against the ground in the direction of 27.0◦ above the forward, horizontal direction to leave the skateboard. Ignore air resistance and the friction between the road and skateboard. What is the maximum height that the skateboarder can reach? (A) 1.05 m; (B) 1.25 m; (C) 1.45 m; (D) 1.65 m; (E) 1.85 m.

You wake up one morning to find yourself in a strange room with opaque walls, and no visible doors or windows. You decide to do some experiments to find out more about your strange situation. Your own body mass is 50.1 kg. You pick up an object and drop it from rest, starting at a height of 1.97 meters above the floor, and it hits the floor 0.380 seconds later. You can ignore air resistance. Based on the outcome of this experiment, when you step on the scale provided for you, what weight will it register for your body? 684 N 911 N 1,367 N 491.5 N

A toy rocket operates by having a spring-loaded tube which ejects a small model rocket when released. The spring inside has a spring constant k = 625N/m, the rocket has a mass of 0.100 kg, and the maximum compression of the spring is 0.18 m. Consider the system of the rocket, spring, and the earth. Consider the interval of time between t1, when the rocket is released from the point of maximum spring compression, and t2, the moment when the spring is fully released and the rocket leaves the launcher. List below the types of energy that are changing during this interval and whether the changes are positive or negative. Please explain how you know.

When some cars are advertised, they quote a "stopping distance" from some speed to zero. The mass of the car and this value of "some speed" give a measure of initial motion, but we aren't necessarily told the mass. Using the stopping distance, one can directly calculate what physical quantity provided by the brakes? A impulse B chemical potential energy C power D kinetic energy E force F velocity G work H acceleration I mass
