13. 

A 30-lb block is initially moving along a smooth horizontal surface with a speed of v1 = 6 ft/s to the left. If it is acted upon by a force F, which varies in the manner shown, determine the velocity of the block in 15 s. The argument for the cosine is in radians.

[A]. v2 = 91.4 ft/s 7
[B]. v2 = 79.4 ft/s 6
[C]. v2 = 91.4 ft/s 6
[D]. v2 = 79.4 ft/s 7
