A block of mass 10kg is initially at rest on a horizontal rough surface. At a time t = 0, a time dependent force (F) acts on it horizontally as shown in the figure. Force (F) stops acting at t = 7 seconds. Consider that coefficient of static and kinetic friction both are equal to 0.5 and` g = 10 ms^(-2)`

A

Maximum kinetic energy acquired by the block is 125 J

B

Maximum kinetic energy acquire by the block is 50 J

C

Total time for which the block is moving with non zero velocity is `5.4s`

D

Total time for which te block is moving with non zero velocity is `7.4`s
