Unformatted text preview: car is a x r =0 and the green car is a x g =220 m. If the red car has a constant velocity of 20 km/hr, the cars pass each other at x = 44.5 m, and if it has a constant velocity of 40 km/hr, they pass each other at x = 76.6 m. What are (a) the initial velocity and (b) the acceleration of the green car? 3) At time t=0, apple 1 is dropped from a bridge onto a roadway beneath the bridge: somewhat later, apple 2 is thrown down from the same height. The diagram below gives the vertical positions y of the apples versus t during the falling, until both apples have hit the roadway. With approximately what speed is apple 2 thrown down?...
