How much tension must a rope withstand if it is used to accelerate a 1210-kg car horizontally along a frictionless surface at 1.20 m/s2?
The tension that a rope must withstand if it is used to accelerate a car horizontally along a frictionless surface.
Answer to Problem 3P
Solution:
Tension on a car along a frictionless surface is .
Explanation of Solution
The tension in a rope that it can withstand if it is used to accelerate a car horizontally i.e. the car is accelerated and horizontal tension is the force exerted horizontally to the car. The expression for the horizontal force or tension is given below:
………… (1)
Here, is the mass of the car and is its acceleration.
Given:
Mass of a car
Acceleration of a car
Formula used:
Calculation:
Substitute, and in equation (1)so the tension is given as follows:
T=ma
=1210 kg(1.20 m/s2)
=1452 N
