please rate it up thanks :)
a bullet hots a wooden block and punches through it. During the penetratio, which of the...
A 15 gr bullet traveling at 500 m/s strikes the 5 kg wooden block and exists the other side at 15 m/s as shown. The wooden block is initially at rest. Determine: a) The velocity of the wooden block just after the bullet exit it b) the average normal force on the wooden block if the bullets passes through it in 1.0 ms (millisecond) c) The time the block slides before it stops The coefficient of kinetic friction between the...
wooden block with mass M 3 kg is lying on a horizontal table and is attached to a spring in its equilibrium position. It is hit by a bullet with mass m 5 g which moves horizontally. The bullet remains in the block after colliding with it. The block moves on the table compressing the spring, with spring constant k 50 Nm, a distance 10 cm. The coefficient of kinetic friction uk 0.2. a) Find the elastic energy stored in...
A bullet mass m1 bounces off a steel block of mass m2 which is resting on a smooth frictionless surface. The initial velocity of the bullet is and the final velocity is -v . A spring with a force constant k is attached to the steel block at one end and attached to a wall at the other. The duration of the impact is delta t . What is the maximum distance through which the spring is compressed

answers pls 1. Determine whether the statements below are true or false: a. [4 points) Two carts move in the same direction along a frictionless track, each acted upon by the same constant impulse. If Cart 1 has the twice the mass of Cart 2, then Cart 2 will have the greater change in linear momentum. b. [4 points) Any force component that causes a centripetal acceleration cannot change the translational kinetic energy of the object. c. [4 points) A...
