Find tangential acceleration component

Reference no: EM1322219

Q1. An automobile whose speed is increasing at a rate of 0.60 m/s2 travels along a circular road of radius 20.0 m. When the instantaneous speed of the automobile is 4.00m/s, find (a) tangential acceleration component, (b) centripetal acceleration component, and (c) magnitude and direction of the total acceleration.

Q2. Speedy Sue, driving at 34.0m/s, enters a one-lane tunnel. She then observes a slow-moving van 175m ahead traveling with velocity 5.40 m/s. Sue applies her brakes but can accelerate only at 2.00 m/s2 since the road is wet. Will there be a collision?
