Question

a 2.964 kilogram truck strikes a fence at 7.00 meters/second and comes to a stop in 1.9 seconds. what was the average force acting on the car

Answer 1

10.92N

Explanation:

Given parameters:

Mass of the truck = 2.964kg

velocity = 7m/s

Time = 1.9s

Unknown;

Average force on the car = ?

Solution:

The force acting on the car is a function of its mass and acceleration according the newton's second law of motion.

   Force = mass x acceleration

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

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

   Force = $\frac{2.964 x 7 }{1.9}$

              = 10.92N
