A car of mass 1000kg is moving at 10m/s when it hits a wall. The force of the car on the wall is 400 N. Calculate the stopping time

25s

Explanation:

Given parameters:

Mass = 1000kg

Velocity  = 10m/s

Force  = 400N

Unknown:

Stopping time  = ?

Solution:

To find the stopping time, we use Newton's second law of motion:

    Ft  = mv

F is the force

t is the stopping time

m is the mass

v is the velocity

        400 x t  = 1000 x 10

                  t  = 25s

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
