A 5000 kg final stage of a spaceship ejects the 10000 kg second stage. Before ejection, the two stages travel with a velocity of 180 m/s. If, after ejection, the second stage travels at 50 m/s opposite the direction of its initial motion, what is the speed of the final stage? Show all work

For each run, determine the kinetic energy (KE = ½ m v2) of the cart just before and after the collision. Enter the values in the Table. Is KE conserved?

Problem 1 (use impulse and momentum method) The 150 kg box is subjected to forces as shown. If it starts from rest, determine its speed after travelling for 10 seconds under the effect of those forces. The coefficient of kinetic friction between the box and the floor is 0.3.

A moving cart collides with a stationary cart. The carts stick together and move at the same speed. Three situations are shown. Identify any that violate the law of conservation of momentum. Note: The bricks on top of the carts have the same mass as the cart. The arrows represent the velocities of the carts. Select all that apply. 0 Before Collision Before Collision Before Collision At Rest At Rest At Rest After Collision After Collision After Collision

If the velocity of an object is tripled and the direction changes from south to north, the momentum will change by a factor of   a negative three. b negative one-third. c positive one-third. d positive three. please show all work, thank you

A 7,300-kg truck runs into the rear of a 1,000-kg car that was stationary. The truck and car are locked together after the collision and move with speed 2 m/s. Compute how much kinetic energy was "lost" in this inelastic collision. ___________ J

A bullet of mass m = 8.00 g is fired into a block of mass M = 220 g that is initially at rest at the edge of a table of height h = and after the impact the block landsd = 1.90 m from the bottom of the table. Determine the initial speed of the bullet. 1.00 m (see figure below). The bullet remains in the block, m/s h d Need Help? Read It Mastor It
