All of the forces of an explosion are so an explosion is considered an isolated system.

a 0.20 kg ball traveling horizontally at 28 m/s, strikes a wall and rebounds at 16 m/s. what is the magnitude of the balls change in momentum durong the rebound?

Answer the guide questions, about the conservation of linear momentum

A 5.3 kg bowling ball is rolled down an alley at 4.2 m/s. A) what impulse is needed to bring it to a stop? b) if it takes 2.3 seconds to accomplish this, what is the applied force (average) draw a picture round significant figures show work

Block "P" of mass Mp slides along an x-axis on a frictionless floor with initial speed Vp,i = 4 m/s. Then it undergoes a one-dimensional collision with stationary block "S" of mass Ms = 0.5 Mp. Next, block "S" undergoes a one dimensional collision with stationary block "U" of mass Mu= 0.5 Ms. Assume that kinetic energy is conserved in each collision. P S ४

Squids rely on jet propulsion when a rapid escape is necessary, providedthey have filled their mantle with water prior to escape. An empty 1.5kg squid initially drifting at 1.6m/s pulls in 0.10kg of water in its mantle, then ejects this water at a remarkable 45m/s. How fast is this squid moving right after filling up with water?

If an object feels an impulse J→ then... a) the velocity of the object must be constant b) the force acting on the object must be constant c) the object's momentum must have changed d) the object's momentum must be constant

You have a mass of 72kg. If you slide on ice at 3.6m/s to greet a 40kg friend who is standing still. As you collide while holding hands what would be there speed do you both move off together
