Question

A skater glides along a circular path of radius 4.70 m. (a) If he coasts around one half of the circle, find the magnitude of thedisplacement vector.
1 m

(b) Find how far the person skated.
2 m

(c) What is the magnitude of the displacement if he skates all theway around the circle?
3 m (a) If he coasts around one half of the circle, find the magnitude of thedisplacement vector.
1 m

(b) Find how far the person skated.
2 m

(c) What is the magnitude of the displacement if he skates all theway around the circle?
3 m

Explanation / Answer

radius r = 4.7 m (a). magnitude of displacement vector = 2r = 9.4 m (b). Distance = r                     = 14.76 m (c). displacment = 0 m
