Question

A coin which is tossed straight up into the air. After it is released it moves upward, reaches its highest point and falls back down again. Use one of the following choices (A through G) to indicate the force acting on the coin for each of the cases described below. Answer choice J if you think that none is correct. Ignore any effects of air resistance.

(A) The force is down and constant
(B) The force is down and increasing
(C) The force is down and decreasing
(D) The force is zero.
(E) The force is up and constant.
(F) The force is up and increasing
(G) The force is up and decreasing

Answer 1

The force acting on the coin as it moves upward, reaches its highest point, and falls back down again is a combination of gravitational force and air resistance.

Step-by-step explanation:

The force acting on the coin as it moves upward, reaches its highest point, and falls back down again is a combination of gravitational force and air resistance. Initially, the force is up and decreasing as the coin moves against the direction of gravity. At the highest point, the force is zero as the coin momentarily stops moving. As the coin falls back down, the force is down and increasing due to the gravitational force pulling it downward.

Answer 2

Answers G, and A

Step-by-step explanation:

the motion of a body is as a result of the various forces acting on it.

As the coin is tossed upwards an upwards force acts on it and this force decreases up to the highest point the coin reaches. at the highest point the force of gravity applies. This force is downwards and constant (9.8m/
`s^(2)`).
