How much time does it take for a truck to slow down if its acceleration is -15m/s2 and the change in velocity is -30m/s

Answer :

quasarJose

Answer:

2s

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  = [tex]\frac{change in velocity}{time}[/tex]

    time  = [tex]\frac{change in velocity }{acceleration}[/tex]  

Now insert the parameters and solve;

   time  = [tex]\frac{30}{15}[/tex]  = 2s
