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

Answer:

2.4m/s²

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  = $\frac{Final velocity - Initial velocity}{time}$

    Acceleration  = $\frac{60 - 0}{25}$    = 2.4m/s³
