Question

What is the force of a 3kg skateboard accelerating at a rate if 4m/s²? Plug the numbers into the formula

Answer 1

Answer:

$\boxed {\boxed {\sf 12 \ Newtons }}$

Explanation:

Force is the product of mass and acceleration.

$F=ma$

The mass is 3 kilograms and the acceleration is 4 meters per square second.

$m= 3 \ kg \\a= 4 \ m/s^2$

Substitute the values into the formula.

$F= 3 \ kg * 4 \ m/s^2$

Multiply.

$F= 12 \ kg*m/s^2$

• 1 kilogram meter per square second is equal to 1 Newton.
• Our answer of 12 kg*m/s² is equal to 12 N

$F= 12 \ N$

The force of the skateboard is 12 Newtons.
