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
