Question 1 • 2003390-Physics 1 Honors Sem. 1 - Peters
Trevor is pulling his younger brother in a wagon. He pulls the wagon 50 m to the corner with a force that is parallel with the ground. He then turns the wagon around and pulls it 50 m back to the starting point with the same force at an angle of 30° with respect to the ground.
Answer
A
They are the same because he uses the same amount of force.
B
They are the same because he travels the same distance.
C
He does less work coming back because the force moving the wagon is only 50cos30°.
D
He does more work coming back because the force moving the wagon is only 50cos60°.
