Beth, a construction worker, attempts to pull a stake out of the ground by pulling on a rope that is attached to the stake. the rope makes an angle of 46.6 ◦ with the horizontal. if beth exerts a force of 124 n on the rope, what is the magnitude of the upward component of the force acting on the stake? answer in units of n.

90.1 N

Explanation:

We are given that

The ropes makes an angle with horizontal=

Beth exerts a force on the rope=124 N

We have to magnitude of the upward component of the force on the stake.

Vertical component is always sin and horizontal component is always cos.

Therefore, the magnitude of the upward component of the force acting on the stake=

The magnitude of the upward component of the force acting on the stake=

The magnitude of the upward component of the force acting on the stake=90.148 N

Hence, the magnitude of the upward component of force acting on the stake=90.1 N

the average speed is 24.57 km/hr
