Question

While braking, an automobile of mass equal to 1320 kg decelerates along a level road at 9.1 m/s2. Assume that all wheels contribute equally to the braking. What is the horizontal force that the road exerts on each wheel of the automobile? Ignore the friction of the air.

Answer 1

F = m*a
m = 1320 kg
a = -9.1 m/s2

Answer 2

thanks got it
