Given : A cyclist is moving along a circular path of radius 98 m with a constant speed 7 m/s.
To Find : Magnitude of displacement of cyclist at 132 s
Solution:
circular path of radius 98 m
=> Circumference = 2πR
= 2 * (22/7) * 98
= 616 m
constant speed 7 m/s.
Time = 132 s
=> Distance = 132 * 7
=> Distance = 924
=> Distance = 616 + 616/2 m
=> one and half circle
=> Displacement = Diameter = 2 * 98 = 196 m
Magnitude of displacement of cyclist at 132 s is 196 m
