Question Question 8
An automobile vehicle has a mass of 1500 kg. What must be the force between the vehicle and road if the vehicle is to be stopped with a negative acceleration of 1.7 ms-2?
Given,
Mass (m) = 1500 kg
Acceleration (a) = -1.7 ms-2
Now, as Force = mass x acceleration
F = 1500 × (-1.7) = -2550 N
Hence, force required = -2550 N. (Negative sign indicates opposite direction.)
