Physics Applying Newtons Laws

Question

A car with a mass of 1,057 kg is being towed by a rope held at a 18° angle to the horizontal. A friction force of 359 N opposes the car’s motion. What is the tension in the rope if the car goes from rest to 15 m/s in 13 s?

Answer 1

First have to find the acceleration through motion equation (a=1.5m/s2)

Then you may find the net force by Newton's second law (Fnet= 1220N)

Same Law Fnet= T-Ff-Fgx

Manipulate the formula then could find T= 4780N
