Let two objects of equal mass m collide. Object 1 has initial velocityv, directed to the right, and object 2 isinitially stationary.

If the collision is perfectly elastic, whatare the final velocities v_1 and v_2 of objects 1 and 2?

A bicyclist was moving at a rate of 8 m/s, and then sped up to 10 m/s. If the cyclist has a mass of 120 kg, how much work was needed to increase his velocity? (Hint: Use the work-kinetic energy theorem.)

An object is moving in a circle. If the radius of the object is doubled, and the period remains constant, the magnitude of the velocity will be ___ original value.

A sprinter starts from rest and accelerates to her maximum speed of 10.5 m/s in a distance of 11.0 m. (a) What was her acceleration, if you assume it to be constant? 0 Incorrect: Your answer is incorrect. Units are required for this answer.

If a free falling rock were equipped with a speedometer, by how much would it's speed readings increase with each second IF it were on a planet where g = 20 m/s^2? would it be 60?
