Question

A crate falls from a helicopter and lands on a very deep snow drift. The snow slows the crate and eventually brings it to a stop. During the time that the crate is moving downward through the snow, is the magnitude of the upward force exerted on the crate by the snow greater than, equal to, or less than the magnitude of the gravitationalforce acting downward on the crate?

Answer 1

Answer:

below

Explanation:

The question is a bit confusing but I will try and answer as best as I can.

• If the crate is slowing falling, this means that the acceleration will be the opposite of the velocity. In terms of the question, since the velocity is going down, the acceleration will be going up.

• Now that we know the acceleration is going up, the force created by the snow has to be more than how much the crate weighs.

• It has to be equal to because in Newtons Third Law, the magnitude of gravitational force created by the snow on the crate has to the be same as the magnitude of gravitational force by the crate itself.

Newtons Third Law states that when two objects come into contact, they create/apply a force that is equal in magnitude but the direction is opposite.

Best of Luck!
