Work all problems on a separate sheet of paper.  Show all work as outlined on board.

Velocity and Acceleration

Velocity=Distance/Time    Acceleration=D Velocity/D Time

What is the velocity, in MPH, of a car traveling 60 miles in 2 hours?

What is the velocity, in MPH, of a car traveling 10 miles in 15 minutes? (be sure to convert minutes to hours)

What is the velocity, in MPH, of a plane traveling 2000 miles in 6 hours?

What is the velocity, in m/s, of a runner traveling 20 meters in 4 seconds?

What is the velocity, in m/s, of a bullet traveling 1200 meters in .1 seconds?

What is the acceleration, in m/s2, of a car speeding up from 0 to 20 m/s in 5 seconds?

Momentum and Force

Momentum=Mass x Velocity    Force=Mass x Acceleration

What is the momentum of a 1000 Kg car traveling at 10 m/s?

What is the force needed to lift a 10 Kg mass?  (Hint:  acceleration = force of gravity)

What is the force needed to accelerate a 1000 Kg car at 2 m/s2?

What is the weight, in Newtons, of a person with a mass of 100 Kg?
