Review. As soon as a traffic light turns green, a car speeds up from rest to 22.35 m/s with constant acceleration 4.02 m/s2. In the adjoining bicycle lane, a cyclist speeds up from rest to 8.94 m/s with constant acceleration 5.81m/s2. Each vehicle maintains constant velocity after reaching its cruising speed. (a) For what time interval is the bicycle ahead of the car? (b) By what maximum distance does the bicycle lead the car? Give it with detailed explanation please.

You are stopped at a red light at a freeway on-ramp. When the light turns green, you use the on-ramp to enter the freeway. The speed limit on the freeway is 60 miles per hour (mph), which is 88 feet/second. Your car can accelerate at a rate of exactly 3.88 ft / s2 . How far, in feet, does it take for your car to accelerate from 0 ft/s to the speed limit? Your answer should be accurate to the...

A cyclist is initially at rest at the origin. At t=0 she starts to accelerate at a constant rate, along a straight road reaching a velocity of 2.60 m/s after 12.0 seconds. 12.0 seconds after starting a prairie dog runs across her path and the cyclist hits the brakes, producing a new constant acceleration. 13.0 seconds after starting, the cyclist has a velocity of 1.50 m/s . C. What is her average acceleration in this 13-s interval? D. What is...
