The answer is -5m/s^2
initial velocity (u)= 40m/s
Final velocity (v)= 0m/s [as brakes are applied]
Time taken=8s
Acceleration = Final velocity - Initial
velocity/ time taken
=0 - 40/8
= -40/8
= -5m/s^2
initial velocity (u)= 40m/s
Final velocity (v)= 0m/s [as brakes are applied]
Time taken=8s
Acceleration = Final velocity - Initial
velocity/ time taken
=0 - 40/8
= -40/8
= -5m/s^2
