Question

what force would be a required to accelerate 40 kg mass by 4m/sec/sec

Answer 1

Answer:

$\boxed {\boxed {\sf 160 \ Newtons}}$

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:

$F= m \times a$

The mass is 40 kilograms and the acceleration is 4 meters per second squared. Substitute these values into the formula.

• m= 40 kg
• a= 4 m/s²

$F= 40 \ kg * 4 \ m/s^2$

Multiply.

$F= 160 \ kg*m/s^2$

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.

$F= 160 \ N$

A force of 160 Newtons is required.
