A tow truck drags a stalled car along a road. The chain makes an angle of 30° with the road and the tension in the chain is 1500 N. How much work is done by the truck in pulling the car 1 km?
Work = Force * distance
The Attempt at a Solution
By drawing a free body diagram, I learn that the horizontal component of tension is 1500 * cos(30), which is apprx 1300 N. I then multiply by 1000 meters to get 1.3 million joules. Is this correct? Is joules always measured in meters or should I have multiplied by 1 instead? Thank You
