A block of mass 2kg is sliding on a smooth surface. At t=0, its speed is `v_(0)=2m//s`. At t=0, a time varying force starts acting on the block in the direction opposite to `v_(0)` if the speed of object is `(38)/(N)m//s` at t=10s. Find the value of N |

Answer» Area=mv`-mv_(0)` `-42=2(v-2)` -21=v-2 `thereforev=-19m//s` |
