Question

The illustration shows people pushing farm carts of equal mass. Each person is pushing with an equal force F in the direction shown.

How does the acceleration of Cart A compare to the acceleration of Cart B?



A.
It is twice the magnitude, but in the opposite direction of cart B's acceleration.

B.
It is twice the magnitude and in the same direction as cart B's acceleration.

C.
It is the same magnitude, but in the opposite direction of cart B's acceleration.

D.
It is the same magnitude and in the same direction as cart B's acceleration.

Answer 1

I can't see the illustration you mention. Could you upload the image or describe the directions of the forces on each cart (which way each F points)?

Tip while you do: acceleration = (net force)/m. The carts have equal mass, so just compare the net forces (vector sum) on A and B to tell whether one acceleration is twice the other, equal, or opposite in direction. If you upload or describe the picture I’ll compute the net forces and give the correct choice.
