For a car moving around a circular track at a constant speed the acceleration is?
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
When you run around a track at 5 km and h your velocity is constant?
sure.
A race car is travelling at constant speed around a circular track What happens to the centripetal acceleration of the car if the speed is doubled?
It increases by a factor of 4, because Fc = (mv2)/r. Fc = ma. so we conclude that the relationship between a and v is a squared relationship.
If a car travels at a constant speed is it accelerating?
No. Acceleration is the change in velocity(speed) over a period time.=====================================Another contributor bristled:Sorry. Velocity and speed are not two different words for the same thing.Velocity means speed and direction, and acceleration means any change in velocity.If the speed is constant but the direction is changing ... like turning a corner or drivingon a circular track ... then velocity is changing, and there is acceleration.
If a jogger jogs around a circular track with a diameter of 275 meters in 14 minutes What was the jogger's average speed in meters per second?
If a jogger jogs around a circular track with a diameter of 275 meters in 14 minutes his average speed (pace) is 1.0285 meters per second.
