Question

Chapter 3, Problem 1DQ

To determine

The direction of acceleration of mass when it is at the end of swing and at midpoint.

Expert Solution & Answer

Answer to Problem 1DQ

There is zero acceleration at end point while direction of tangential acceleration changes from zero.

Explanation of Solution

When the mass reaches at end points the tangential force acts on the mass towards the mean position which results the net acceleration acts towards midpoint.

When the mass reaches at the midpoint, the gravitational force balances the tension in the string. So the resultant force on the mass is zero which results the net acceleration becomes zero.
