Multiple Choice

A particle of mass $5.7 \mathrm {~kg}$ , initially at rest, experiences a time-varying force, $f ( t ) = c t ^ { 2 } + h t$ , where $c = 1.3 \mathrm {~N} / \mathrm { s } ^ { 2 }$ and $h = 5.6 \mathrm {~N} / \mathrm { s }$ . What is the velocity of the particle at time $t = 4$ seconds?

A) 35 m/s
B) 19 m/s
C) 13 m/s
D) 25 m/s
