The acceleration of a bus is given by a(t) = at, where a =1.2m/s^3.

a) If the bus's velocity at time t = 1.0s is 5.0m/s, what is its velocity at time t = 2.0s ?

b) If the bus's position at time t= 1.0s is 6.0m, what is its position at time t = 2.0s?

c) Sketch ay -t, vy -t, and x -t graphs for the motion.
