A block of mass 0.2 kg is launched by a spring k1= 2.0 N/m. The block moves along a frictionless horizontal table and pushes another spring, k2 = 2.3 N/m , to the maximum deflection x. If the initial deflection of the spring k1 is 0.050 m, what is the maximum deflection of spring k2? Consider that the masses of the springs are negligible.

A machine gun, of mass 35.0 kg, fires 50.0-gram bullets, with a muzzle velocity of 750 m/s, at the rate of 300 rounds per minute. What is the average force exerted on the machine gun mount?   Group of answer choices: 94.0 N 438 N 219 N 188 N

A student performs a ballistic pendulumexperiment using an apparatus. Initially the bullet is fired at the block while the block is at rest (at its lowest swing point).After the bullet hits the block, the block risesto its highest position, and continues swinging back and forth.The following data is obtained: the maximum height the pendulum rises is2.9 cm, the mass of the bullet is 67 g, and the mass of the pendulum bob is 822 kg. Find the final velocity of the system (m1 + m2) immediately after the collision and before the pendulum starts to swing upward. The acceleration of gravity is 9.8 m/s^2.Answer in units of m/s.

A mass M1 (of 2.5 kg) slides without friction on a table at a speed of 5 m/sec towards a mass M2 of 5 kg which can also slide without friction on the table. There is a spring on the face of M2 that will contact M1. If the spring constant is 100 N/m, what will be the maximum compression of the spring?

On a flat, frictionless table, two blocks (B1 of mass 2.00 kg and B2 of mass 3.00 kg) are pressed together against either end of an ideal massless spring. The spring stores 75.0 J of elastic potential energy. The blocks are not attached to the spring. What will the coefficient of restitution be if both blocks are released simultaneously?

A 30.2 N net force is applied for 15.64 s to a 10.2 kg box initially at rest.  What is the speed of the box at the end of the 15.64 s interval? Use g=9.8m/s.

A baseball with mass m=m=0.145 kg is dropped from rest from a height of h=h=5.9 m above a baseball catcher's glove. After falling the given height, the glove stops the ball in a time t=t=0.0162 s.Write an expression for the magnitude of the force, FF, exerted on the ball by the glove as the ball is being caught. Your answer will include the symbol gg, which is the acceleration of gravity at the Earth's surface. And what is the magnitude, in newtons, of the force FF?

Two forces, F1 = (3.90î − 2.60ĵ) N and F2 = (3.65î − 8.05ĵ) N, act on a particle of mass 2.10 kg that is initially at rest at coordinates (+1.60 m, +3.50 m).
