Two asteroids bump in space. The larger one has a mass of 3000 kg and the smaller one has a mass of 100 kg. If the force of the collision is 10,000 newtons on each asteroid, what are their accelerations? a.

Which two phrases best describe cells?

A block of mass 1.3 kg is resting at the base of a frictionless ramp. A bullet of mass 50 g is traveling parallel to the ramp surface at 250 m/s. It collides with the block, enters it, and exits the other side at 100 m/s.
