Physics Worksheet – Unit 4.2
1. A man is pulling on his dog with a force of 70 N directed at an angle of 30 degrees to the horizontal. Find
the x and y components on this force.
2. A gust of wind blows an apple from a tree. As the apple falls, the gravitational force on the apple is 2.25 N
downward, and the force of the wind on the apple is 1.05 N to the right. Find the magnitude and direction of the
net force of the apple.
3. The wind exerts a force of 452 N north on a sailboat, while the water exerts a force of 325 N west on the
sailboat. Find the magnitude and direction of the net force on the sailboat.
4. If a car is traveling westward with a constant velocity of 20 m/s, what is the net force acting on it?
5. If a car is accelerating downhill under a net force of 3674 N, what additional force would cause the car to
have a constant velocity?
6. A sensor on a crash test dummy reads a force of 130 N forward and a force of 4500 N on the right side.
What net force would be recorded?
