During a ballistic test a 0.15 kg bullet moving with 60 m/s hits a sandbag and exits from the other side with a velocity of 12 m/s. Sandbag has a thickness of 1.44 m and it applies constant force. a) Using kinematics equations, find the average velocity and the time for the bullet to pass through the sandbag. b) What is the average force exerted by the sandbag?

Ballistic Cylinder A 0.17-kg bullet is fired with a velocity of 85.9 m/s into a solid cylinder of mass 10.1 kg and radius 0.31 m. The cylinder is initially at rest and is mounted on a fixed vertical axis that runs through its center of mass. The line of motion of the bullet is perpendicular to the axis and at a distance d 0.0059 m from the center. Find the angular speed of the system after the bullet strikes and...
A bullet of mass 0.0018 kg moving at 472 m/s embeds itself in a large fixed piece of wood and travels 0.61 m before coming to rest. Assume that the deceleration of the bullet is constant. 1. What force is exerted by the wood on the bullet? F =
A 13.0 g bullet is moving to the right with speed 250 m/s when it hits a target and travels an additional 25.0 cm into the target. What are the magnitude (in N) and direction of the stopping force acting on the bullet? Assume the stopping force is constant. magnitude N?

Ballistic and Springs-- An 8g bullet is shot into a 2.2-kg block of wood thatis initially at rest. The bullet embeds in the block, and together they slide on a horizontal frictionless surface at 1.2 m/s towards on unstrained ideal spring that is fixed to a wall. The spring is compressed by the block as it comes to a momentary stop. Ignore the effects of air resistance. (a) What is the velocity of the bullet immediately before it hits the...
A 0.012-kg bullet, traveling at 850 m/s, hits a 2-kg block of wood that is initially at rest, and goes straight through it. Assume that the final velocity of the bullet relative to the block is 400 m/s, and that the system is isolated. (a) What is the coefficient of restitution for this collision? (b) How much kinetic energy is “lost” in the collision? (c) What is the final velocity of the block?
A bouncy, elastic ball of mass 1.20 kg moving with v = 5.70 m/s hits the wall at an angle of 30° and bounces off. If the collision lasted for 0.01 s, what is the average force exerted by the wall on the ball?
