Motion and Force Homework Problems
Name:__________________________ Date:____________ Period:______
Work all problems on a separate sheet of paper. Show all work as outlined on board and in your notes.
Velocity and Acceleration
Velocity=Distance/Time Acceleration=D Velocity/D Time
What is the velocity, in MPH, of a car traveling 100 miles in 2 hours?
What is the velocity, in MPH, of a car traveling 20 miles in 20 minutes? (be sure to convert minutes to hours)
What is the velocity, in MPH, of a plane traveling 6000 miles in 13 hours?
What is the velocity, in m/s, of a runner traveling 120 meters in 60 seconds?
What is the velocity, in m/s, of a bullet traveling 3200 meters in .2 seconds?
What is the acceleration, in m/s2, of a car speeding up from 0 to 10 m/s in 10 seconds?
Momentum and Force
Momentum=Mass x Velocity Force=Mass x Acceleration
What is the momentum of a 2000 Kg car traveling at 5 m/s?
What is the force needed to lift a 120 Kg mass? (Hint: acceleration = force of gravity)
What is the force needed to accelerate a 1200 Kg car at 3 m/s2?
What is the weight, in Newtons, of a person with a mass of 80 Kg?
