Question

a truck starts from rest and accelerates for 25 seconds to reach a velocity of 60m/s . calculate the rate of acceleration for the truck

Answer 1

2.4m/s²

Step-by-step explanation:

Given parameters:

Initial velocity = 0m/s

Time 25s

Final velocity = 60m/s

Unknown:

Acceleration = ?

Solution:

Acceleration is the rate of change of displacement

Acceleration =
`(Final velocity - Initial velocity)/(time)`

Acceleration =
`(60 - 0)/(25)` = 2.4m/s³
