Question

A bus starts from rest. If the acceleration of the bus is 1.5 m/s2, calculate its final velocity after 20 seconds. ( Ans - 30 m/s )

Answer 1

Answer:

v = 30 m/s

Explanation:

given that

initial velocity = 0m/s

time = 20 s

acceleration = 1.5 m/s^2

to find; final velocity

using v=u+at formula

v = 0+1.5*20

v = 1.5*20

v = 30 m/s
