Answer to Question #165654 in Mechanics | Relativity for Humble Joseph Johnson

Question

A truck off the from rest and cover a distance of 120m on a straight road in 20 second

Calculate the acceleration

Answer 1

Total distance covered(s) = 120 m

Time taken(t) = 20 s

Initial velocity of particle(u) = 0 m/s

Final velocity(v) = $\dfrac{s}{t}=\dfrac{120}{20}m/s$

= $6m/s$

Acceleration = $\dfrac{v-u}{t}=\dfrac{6}{20}m/s^2$

= $0.3m/s^2$
