AP Physics 1· difficulty 1/5

A net horizontal force of 15 N15~\text{N} accelerates a 5.0 kg5.0~\text{kg} crate on a frictionless surface. What is the crate's acceleration?

  • A

    75 m/s275~\text{m/s}^2

  • B

    3.0 m/s23.0~\text{m/s}^2

  • C

    5.0 m/s25.0~\text{m/s}^2

  • D

    0.33 m/s20.33~\text{m/s}^2

Explanation

a=Fnet/m=15/5.0=3.0 m/s2a = F_{\text{net}}/m = 15/5.0 = 3.0~\text{m/s}^2.
