Question

A 2.964 kilogram truck strikes a fence at 7.00 meters/second and comes to

Answer 1

10.92N

Explanation:

Given parameters:

Mass of truck = 2.964kg

Velocity of truck = 7m/s

Time taken = 1.9s

Unknown:

Average force on the car = ?

Solution:

According to newton's third law of motion "action and reaction are equal and opposite".

The force with which the truck struck the fence is the same as the force the fence acted on the truck with but in another direction.

 From newton's second law:

      Force  = mass x acceleration

      We know that acceleration is the change in velocity with time;

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

   Force =  mass x  $\frac{change in velocity }{time }$

  Force = $\frac{2.964 x 7}{1.9}$ = 10.92N
