A 3-kg rock is thrown upward with a force of 200 N at a location where the local gravitational acceleration is 9.79 m/s^2. Determine the acceleration of the rock, in m/s^2.
Show me the final answer↓
Let us first calculate the weight of the rock using the following equation:
(Where W is weight, m is mass and g is acceleration due to gravity)
Substitute the values we know:
We will now calculate all the forces that affect the rock (net force):
Let us now calculate the acceleration using Newtons second law.
(Where F is force, m is mass and a is acceleration)
Substituting the values we know gives us:
