a constant force acting on a body of mass 3 kg and changes its speed from 2 metre per second to 3.5 M per second in 25 seconds that the direction of motion remain unchanged what is magnitude and direction of force |

Answer» HII bro here U can see the mass m=3kg and speed is u=2m/s and v=3.5m/s also the time is 25 SECS so, we know that F= ma and a= v-u/t therefore, a=3.5-2/25 =0.06 F= 3×0.06 =0.18 N |
