Question #16835

a car accelarates from 0/ms to 30/ms in 5 second has an accelaration of...........m/s2?

Expert's answer

Let a be the acceleration.

Then the velocity v changes in time t by the

formula

v = at

hence

a = v/t = 30/5 = 6 m/s^2

Then the velocity v changes in time t by the

formula

v = at

hence

a = v/t = 30/5 = 6 m/s^2
