Question

1. A particle travels counterclockwise around a circle of 36m radius so that the distance from a fixed point 0 on the right end of a horizontal diameter is given by s=20t + 2t2where s is in meters and t is in seconds. Compute the rectangular components of acceleration at the end of 2 seconds.

2. The particle has an initial velocity of 88mps up to the right at a slope of 4/3. The rectangular components of acceleration are constant at ax=-4m/s2 and ay=-20m/s2. Compute the radius of curvature at the start and at the top of the path.
