An automobile vehcile has a mass of `1500 kg` What must be the force between the vehcile and road if the vehcile is to be stopped with a negative acceleration of `1.7 m//s^(2)` ? |
|
Answer» Here, `m=1500 kg, a = -1.7 m//s^(-2), F = ?` clearly, `F= ma = 1500 (-1.7) N = -2550N` Negative sign indicates that force is opposing the motion of the vehcile. |
