Question

A particle is moving in a circle of radius 4 cm with constant speed of 1 cm/s. Find
a) time period of the particle.
b) average speed, average velocity and average acceleration in a time interval from t = 0 to
1 =T/4. Here, T is the time period of the particle. Give only their magnitudes.​

Answer 1

Explanation: 4 circumference of circle=2pir

                                                                  =2*22*4/7

                                                                  =25.15 cm

                        time period = 25.15/1= 25.15 s

                        average speed = 25.15/25.15= 1 m/s        

                        average velocity = 0/25.15=0

                       average acceleration= v/t=0/25.15=0
