Question

A truck starts from rest and gains a velocity of 20 km/hr in 8 seconds while moving on a straight road. What is the acceleration of the truck?

Answer 1

Step-by-step explanation:

a=v/t

20/8

5/2

this could be the answer

Answer 2

Answer:

Initial Velocity ( u ) = 0 m/s

Final Velocity ( v ) = 20 m/s

Time taken ( t ) = 8 seconds

Acceleration ( a ) = v - u / t = 20 - 0 / 8 = 20 / 8 = 2.5 m s^-2.
