Question

A traveler pulls on a suitcase strap at an angle 36° above the horizontal. If 250 J of work are done by the strap while moving the suitcase a horizontal distance of 10 m, what is the tension in the strap?

1) 68 N
2) 56 N
3) 45 N
4) 63 N

Answer 1

The tension in the strap is 63 N.

Step-by-step explanation:

To find the tension in the strap, we can use the formula: work = force * distance. In this case, the work done is 250 J and the distance moved is 10 m. However, the force is being applied at an angle, so we need to find the horizontal component of the force.

The horizontal component of the force is given by: force * cos(angle). Plugging in the values, we get: tension * 10 m = 250 J * cos(36°)

Solving for tension, we find: tension = 250 J * cos(36°) / 10 m = 63 N

Therefore, the tension in the strap is 63 N.
