-) The velocity-time graph of an electronic toy car travelling in a straight line is shown in the figure below.velocity (m/s) a. Determine the velocity at time42S. b. Determine the

average velocity of the toy car from time = 0 s to time = R s, where R = At time = 0 s, a second toy car that is 500 m away starts travelling in the opposite direction with a constant velocity of Determine the time that the two toy cars will meet.
