Question

Two men decide to use their cars to pull a truck stuck in mud. They attach ropes and one pulls with a force of 794 N at an angle of 26• N of E, while the other car pulls with a force of 1111N at an angle of 17• S of E. What is the net forward force exerted on the truck in the direction it is headed?

Answer 1

Solution)

Here,

Consider Man 1,

We have

Fx = 794 cos(26)

Fx = 713.64 N

Now, Consider Man 2

We have,

Fx = 1111 cos(17)

Fx = 1062.45 N

Here, both men are pulling in the same direction, hence,

Net force = 713.64 N + 1062.45 N

Net force = 1776.09 N
