An ice skater glides around a rink at a constant speed of 2 m/s. Is the skater accelerating?
Yes. To skate "around" a rink, the direction of motion must change at the ends of the rink.
In addition, figure skaters usually glide on an inside or outside edge of the skate, which requires a curved path. They seldom skate in a straight line. If they do, points are deducted.
no, because he is at a constant speed, whenever you have a constant speed there is no acceleration
my bad, drwls is right, didn't take for account that it's around the rink, so there's the centripetal acceleration to take for account
