A car standing from rest accelerates uniformly and attends a speed of 60ms-1 in 30 seconds. It then slows down uniformly until it comes to rest in the next 20 seconds. Sketch the velocity time graph for the motion of the car

Acceleration during the first 30 seconds is "a_1 = \\frac{60m\/s}{30s} = 2 \\frac{m}{s^2}" and during the next 20 seconds is "a_2 = \\frac{-60m\/s}{20s} = -3 \\frac{m}{s^2}".
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
