Question

A bus traveling at 4∙8ms-1decelerates at 2∙4ms-2. Calculate the time taken for the bus to come to a complete stop

Answer 1

Explanation:

u = 4.8 m/sec, a = - 2.4 m/sec² , t = ? v = 0

v = u + at

0 = 4.8 + (-2.4) * t

0 = 4.8 - 2.4 * t

- 4.8 = - 2.4 * t

therefore t = -4.8/-2.4 = 2 second
