Answer:
Step-by-step explanation:
We are asked to calculate the force needed to accelerate a 40 kilogram mass by 4 meters per second per second.
According to Newton's Second Law of Motion, force is the product of mass and acceleration. Therefore, the formula is:
The mass is 40 kilograms and the acceleration is 4 meters per second squared. Substitute these values into the formula.
Multiply.
Convert the units. 1 kilogram meter per second squared is equal to 1 Newton. Our answer of 160 kilogram meters per second square is equal to 160 Newtons.
A force of 160 Newtons is required.
