A block of mass 2.00 kg moving at a speed of 10.0 m/s accelerates at 3.0 `m/s^2` for 5.00 s. Compute its final kinetic enegy.

Text Solution

Verified by Experts

The correct Answer is:
B

`M_b=2kg,u=10m/sec`
`a=m/sec^2,t=5sec`
`v=u+at`
`=10+3xx5=25 m/sec`
`:. FiN/Al K.E. =1/2 mv^2`
`=1/2xx2x625=625J`
