Change in Momentum and Impulse

AP Physics 1· difficulty 2/5

0 2 8 15 t (s) F (N)

A constant force of 15 N15~\text{N} acts from t=2 st = 2~\text{s} to t=8 st = 8~\text{s}. The impulse delivered is

  • A

    30 N⋅s30~\text{N·s}

  • B

    90 N⋅s90~\text{N·s}

    check_circle
  • C

    15 N⋅s15~\text{N·s}

  • D

    60 N⋅s60~\text{N·s}

Explanation

Impulse = area = 15×6=90 N⋅s15 \times 6 = 90~\text{N·s}.
