Question

A car is traveling due west at 20m/s.find the velocity of the car after  3s if it’s acceleration is 1m/s2 due East . Assume that the acceleration remains constant.

oobleck · Answer

what does acceleration mean? Every second, the velocity increases by 1 m/s So, after 3 seconds, it has increased by 3 m/s But, the acceleration is in the opposite direction, so v decreases by 3 m/s

V = Vo + a*T = -20 + 1*3 = ----m/s.
