Newton's laws quiz
Five questions on Newton's laws. Answer all 5 to see your score.
Question 1 of 5
A 1500 kg car accelerates at 2.0 m/s^2. What net force does the engine-drivetrain system produce on the car?
Question 2 of 5
A worker pushes a box across a rough floor at a steady 40 N, and the box slides at constant velocity. What is the friction force on the box?
Question 3 of 5
A 5.0 kg block is released from rest on a frictionless 30 degree incline. What is its acceleration down the slope? Use g = 9.8 m/s^2.
Question 4 of 5
A 60 kg person stands in an elevator that is accelerating downward at 2.0 m/s^2. What force does the floor exert on them? Use g = 9.8 m/s^2.
Question 5 of 5
On a flat road, the tires of a car have a static friction coefficient of 0.50 with the pavement. What is the fastest speed at which it can round a curve of radius 40 m without skidding? Use g = 9.8 m/s^2.
