1. A 70-kg runner exerts a horizontal force of 60 N. What is the acceleration of
the runner?
2. A crate is dragged across an ice-covered lake. The crate accelerates at
0.5m/s and is pulled by a force of 62N. What is the mass of the crate?
3. A sports car accelerates from rest to 35m/s in 5.3 seconds. The car exerts a
force of 4123N. What is the mass of the car?
4. Three women push a stalled car. Each woman pushed with a 400N force.
What is the mass of the car if the car starts from rest and moves 9 meters in
5seconds?
5. A sled is pulled along an ice-covered lake. The mass of the sled is 25 kg. The
net force acting of the sled is 31 N. How fast will the sled be moving if it starts
from rest and is pulled with the constant force of 31N for 5 seconds?
