Determine acceleration of the bullet while moving into clay : A bullet is moving at a speed of 367 m/s when it embeds into a lump of moist clay. The bullet penetrates for a distance of 0.0621 m. Determine the acceleration of the bullet while moving into the clay. (Assume a uniform acceleration.)

Rocket-powered sleds are used to test the human response : Rocket-powered sleds are used to test the human response to acceleration. If a rocket-powered sled is accelerated to a speed of 444 m/s in 1.8 seconds, then what is the acceleration and what is the distance that the sled travels?

Find the magnitude of the acceleration : A hanging mass, M1 = 0.18 kg, is attached by a light string that runs over a frictionless pulley to the front of a mass M2 = 0.47 kg that is initially at rest on a frictionless table. A third mass M3 = 0.71 kg, which is also initially at rest on a fr..
