Question 20

Multiple Choice

  A body is acted on by an impulsive force from time t = 0 to time t = 10 ms. During this time, the force decreases uniformly from 10<sup>3</sup> N to zero as shown in the graph. The change in momentum of the body during this interval is A)  10 kg · m/s B)  5.0 kg · m/s C)  0.16 kg · m/s D)  10<sup>5</sup> kg · m/s E)  a value that cannot be determined from this graph.
