A towrope is used to pull a 1750-kg car, giving it an acceleration of +1.35 m/s ^2. What force does the rope exert?
Newton's 2nd law of motion:
Force = (mass) x (acceleration)
= (1,750 kg) x (1.35 m/s²)
= 2,362.5 Newtons
(about 531 pounds)
Answer:
Force, F = 2362.5 N
Explanation:
Given that,
Mass of the car is 1750 kg
Acceleration of the car is +1.35 m/s^2
To find :
The force exerted by the rope.
Solve :
Let F is the force exerted by the rope. The force by an object is given by the product of mass and its acceleration. It is also known as Newton's second law.
\(F=ma\)
\(F=1750\ kg\times 1.35\ m/s^2\)
F = 2362.5 N
Therefore the force exerted by the rope is 2362.5 N.
