A sedan car of mass 200kg is moving with a certain velocity . It is brought to rest by theapplication of brakes, within a distance of 20m when the average resistance being offered to it is 500N.What was the velocity of the motor car? |

Answer» Given, Mass = 200kg Distance = 20m Force = 500N To FIND:- Velocity of the MOTOR car By APPLYING F = maa = f/m= 500/200 = 2.5m/s^2 By applying v^2-u^2=2asv^2 - 0^2 = 2×2.5×20 v^2 = √100 v = 10m/s. |
