Question

a pendulum wiht a cord length of 1 m swings in a vertical plane, when the pendulum is in the two horizontal ositions 90 and 270 its speed is 5 m/s what is the magnitude of the radial accelertaion

Answer 1

The magnitude of the radial acceleration of pendulum is 25 rad/s²

What is acceleration?

Acceleration can be defined as the rate change of velocity with time.

acceleration a = (Δv) / (Δt)

The centripetal acceleration or radial acceleration for the pendulum is given by

a = v²/r

Given is the radius = cord length of pendulum =1m and the velocity v = 5m/s, then the acceleration will be

a = (5)² /1

a = 25 rad/s²

Thus, the radial acceleration is 25 rad/s²
