A truck starts from rest and accelerates...

A truck starts from rest and accelerates uniformly to a velocity of 40m/s in 10s, it then runs with this uniform velocity and is finally brought to rest in 50m by a uniform deceleration. If the total run of the truck is 500m, find its acceleration and total time of journey.

Text Solution

AI Generated Solution

To solve the problem step by step, we will break down the truck's journey into three parts: acceleration, constant velocity, and deceleration. ### Step 1: Calculate the acceleration during the first part of the journey. The truck starts from rest and accelerates uniformly to a velocity of 40 m/s in 10 seconds. - **Initial velocity (u)** = 0 m/s (since it starts from rest) - **Final velocity (v)** = 40 m/s ...
