You give a toy car an initial velocity of 1.20 m/s directed up a ramp. The car takes a total of 2.00 s to roll up the ramp and then roll back down again into your hand. Assume that you catch the car at the same point from which you released it, and that the acceleration is constant through the entire motion. (a) Determine the magnitude of the car's acceleration. ________ m/s2 (b) Determine the total distance traveled by the...
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.
A car moves on a flat road with initial velocity vector v1,x = 9.41 m/s and v1,y = -2.37 m/s, then accelerates for 6.53 seconds at an average acceleration of aav,x = -0.102 m/s2 and aav,y = 0.102 m/s2.
