The answer is b because I just know it is
Pretty sure it’s force so C
Hope this helps :)
Answer:

Explanation:
The equation for force is given:

First, we must find the total mass, which is the sum of the boy's mass and the go-cart's mass.
- total mass= boy's mass + go cart's mass
The boy's mass is 35 kilograms and the go cart's is 65 kilograms.
- total mass= 35 kg+ 65 kg=100 kg
Now we know the total mass and the acceleration.

Substitute the values into the formula.

Multiply.

- 1 kilograms meter per square second is equal to 1 Newton.
- Our answer of 500 kg*m/s² is equal to 500 Newtons.

The force exerted by the go cart engine is <u>500 Newtons.</u>

= 6.3715 μm^3
1 μm^3 = 10^-12 cm^3
6.3715 μm^3 = 6.3715 x 10^-12 cm^3
==> 6.4 x 10^-12 cm^3
