A racing car has uniform acceleration of 15m/s2 . How much distance will it cover in 5 s after the start? (187.5m) |

Answer» tion:You can calculate the acceleration of an object from its CHANGE in velocity and the time taken. Velocity is not EXACTLY the same as SPEED. Velocity has a DIRECTION as well as a speed. For example, 15 m/s is a speed, but 15 m/s North is a velocity (North is the direction). |
