Question

Phil is riding a scooter and pushes off the ground with his foot. this causes him to accelerate at 12 m /s. Phil weighs 600 N. how strong was his push off the ground?​

Answer 1

Answer:

734.16 kg m/$s^{2}$

Explanation:

The problem is asking for the Force of pushing off the ground.

• The formula of Force is: F = mass x acceleration

Given = Mass: 600 newtons (N)

             Acceleration: 12 m/$s^{2}$

We have to convert the mass into kg first. Remember that 1 kg is equal to 9.80665 newtons.

Let x be the mass in newtons.

Let's convert: $\frac{1 kg}{9.80665 N}$ x $\frac{x}{600 N}$ = $\frac{600}{9.80665}$ = 61.18 kg

Phil's weight is 61.18 kg

Let's go back to finding the force.

F = m x a

F = 61.18 kg x 12 m/$s^{2}$

F = 734.16 kg m/$s^{2}$
