Question

Can some one help me with this please, I think I got it right but would like to make sure.

Problem 12.166 12 of 13> Part A Determine the acceleration of the particle at θ-34°. The particle starts from rest at θ Express your answer to three significant figures and include the appropriate units. A particle is moving along a circular path having a radius of 6.3 in. such that its position as a function of time is given by 0 sin 3t, where 0 and the argument for the sine are in radians, and t is in seconds. Value Unis Units Submit Provide Feedback Next>

Answer 1

In a circular motion, the particle has two components of acceleration viz. radial and tangential.

The tangential part of acceleration is the rate of change of velocity of the particle in circular motion. While the radial acceleration refers to the change in direction of velocity of the particle in circular motion.

Note: Here I am not sure about which acceleration it is asked, anyway, I have calculated both the radial and tangential acceleration and also the net acceleration. Hope it is clear.

Please feel free to ask in case of any doubt and discrepancies.
