Answer:
Explanation:
We are asked to find the mass of a cabinet, given the force and acceleration. According to Newton's Second Law of Motion, force is the product of mass and acceleration. The formula for this is:
The force is 200 Newtons, but we should convert the units to make unit cancellation easier. 1 Newton is equal to 1 kilogram meter per second squared, so the force of 200 Newtons is 200 kilogram meters per second squared.
The mass is unknown and the acceleration is 4 meters per second per second or 4 meters per second squared.
- F= 200 kg*m/s²
- a= 4 m/s²
Substitute the values into the formula.
We are solving for the mass, m, so we must isolate the variable. It is being multiplied by 4 meters per second squared. The inverse operation of multiplication is division. Divide both sides by 4 m/s²
The units of meters per second squared cancel.
The mass of the cabinet is <u>50 kilograms.</u>
