Jenny is sitting on a sled on the side of a hill inclined at 15°. What force is required to keep the sled from sliding down the
hill if the combined weight of Jenny and the sled is 90 pounds?

Respuesta :

Answer:

504 N

Explanation:

The force that starts the sled to slide down is:

F = mg sin Ф = 90lb * 9.81m/s² * sin 15° = 198.4kg * 9.81m/s² * sin 15°

The force is 504 N.

How to find the force?

It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied.

The force that starts the sled to slide down is:

F = mg sin Ф = 90lb * 9.81m/s² * sin 15°

= 198.4kg * 9.81m/s² * sin 15°

= 504 N

Height is the measurement of an object within the vertical direction and distance is the measurement of an item from a selected factor within the horizontal route.
