Calculate the difference in velocity, Then divide that by the time. The result will be the acceleration, in this case, in meters per second squared.

The the skater is accelerating. Acceleration is the rate at which an object changes its velocity. Velocity is a measure of speed and vector (direction). Even though the skater is traveling at a constants speed, the skater is going in a circle around the rink so the direction is changing. Therefore the velocity is changing. Therefore the skater is accelerating.

Acceleration is change in velocity. These are vectors that have magnitude and direction. Changing either magnitude (speed) or direction will have the skater be accelerating. SO, if the skater is going at a constant speed of 2m/s in a straight line, he is not accelerating. If he is at a constant speed of 2m/s traveling in a circle (you gave the word "around"), he is accelerating. Going around in circles means there is a force constantly changing your direction. Obviously that force is coming from the skaters legs.

He is an entertainment photograher Shoot celebrities for studios. Kind of a staff photography for the studios. He was a gymnast and pro inline skater. NOT a pro skateboarder.

her acceleration would be 5 m/s2 because F=ma, or Force=mass x accelration, therefore 300 N= 60kg x acceleration.
