A car is traveling at a constant speed of 20m/s on a straight road. As the car passes a large billboard, a motorcycle rider is cruising on the same road at a speed of 12m/s. The motorcycle is 1 km behind the car as the car passes the billboard. The motorcycle increases its speed and catches up with the car 3km from the large billboard(assume in a parallel lane).

for a squared unit, input^ for example. square metres would be m^2

answer the following questions, giving the results in to 2 decimal places in SI units. A. What was the acceleration of the motorcycle? B. How much time elapsed from the car's passing the billboard to the motorcycle catching up? C. What was the speed of the motorcycle when it caught up to the car?
