Explanation:

Given parameters:

Acceleration of the truck = 15m/s²

change in Velocity = 30m/s

Unknown:

Time taken for the body to slow down = ?

Solution:

Acceleration is the rate of change of velocity ;

Acceleration = $\frac{change in velocity}{time}$

time = $\frac{change in velocity }{acceleration}$

Now insert the parameters and solve;

time = $\frac{30}{15}$ = 2s
