Randall D. Knight — Dynamics II: Motion in a Plane: Problem 47

A 2.0 kg pendulum bob swings on a 2.0-m-long string. The bob’s speed is 1.5 m/s when the string makes a 15° angle with vertical and the bob is moving toward the bottom of the arc. At this instant, what are the magnitudes of (a) the bob’s tangential acceleration, (b) the bob’s radial acceleration, and (c) the tension in the string?

📝 Solution Approach

Given: 2.0 kg, 1.5 m

Find: (a) the bob’s tangential acceleration; (b) the bob’s radial acceleration; (c) the tension in the string?
