Problem

Two carts, A and B, are pushed separately along a frictionless horizontal track by identical constant horizontal forces of magnitude

10\,\text N

. Cart A has mass

2\,\text{kg}

, and cart B has mass

4\,\text{kg}

. Which of the following correctly compares the magnitudes of their accelerations

a_A

and

a_B

? (a)

a_A = a_B

(b)

a_A = 2\,a_B

(c)

a_A = \dfrac12\,a_B

(d)

a_A = 4\,a_B
