Answer:
4.1s
Explanation:
Given parameters:
Force applied = 1.26 x 10⁴ N
Mass of the truck = 2.3 x 10³kg
Speed of the truck = 22.2m/s
Unknown:
The time it will take to stop the truck = ?
Solution:
To solve this problem, we must understand that the momentum must be conserved.
So;
Momentum of the truck = Impulse applied on it
mass x velocity = Force x time taken
So;
Time taken = [tex]\frac{nass x velocity }{force }[/tex] = [tex]\frac{2300 x 22.2 }{12600}[/tex] = 4.1s
