Question
A car traveling at 70 km/h. It then accelerates at 3.6m/s^2 to 90km/h. How long does it take to reach a new speed. How far does it travel during acceleration

90 km/h = 25.00 m/s
70 km/h = 19.44 m/s
Divide the speed change by the acceleration to get the time required.
t = (5.56 m/s)/3.6m/s^2 = 1.54 s
Multiply time by average speed for the distance.
1.54 * (25+19.44)/2 = ____
