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

Answer :

QUASARJOSEGO

Answer:

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
