As the engineer working in a car company, you are assigned to evaluate two new car models, the Car A and the Car B car variants. The two cars begin their test drive from rest side by side and travel along a straight highway. For 10 seconds, Car A accelerates at 4 m/s2 and then maintains a constant speed. Next, the Car B accelerates at 5 m/s2 until reaching a constant speed of 25 m/s and then maintains this speed. (b)Calculate and sketch the a-t, v-t, and s-t graphs for the Car B until t = 15 s.

1. a) A steel ball is dropped from a building's roof and passes a window, taking 0.13 s to fall from the top to the bottom of the window, a distance of 1.20 m. It then falls to a sidewalk and bounces back past the window, moving from bottom to top in 0.13 s. Assume that the upward flight is an exact reverse of the fall. The time the ball spends below the bottom of the window is 1.93 s. How tall is the building? b) A basketball player grabbing a rebound jumps 74.1 cm vertically.
