How long will it take a - 1.26 * 10 ^ 4 force to stop a 2.30 * 10 ^ 3 truck moving at a speed of 22.2 m/s?

4.1s

Explanation:

Given parameters:

Force applied  = 1.26 x 10⁴ N

Mass of the truck  = 2.3 x 10³kg

Speed of the truck  = 22.2m/s

Unknown:

The time it will take to stop the truck  = ?

Solution:

To solve this problem, we must understand that the momentum must be conserved.

 So;

      Momentum of the truck  = Impulse applied on it

              mass x velocity  = Force x time taken

So;

      Time taken  =    =   = 4.1s
