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>

We have the final answer as
<h3>25 J</h3>
Hope this helps you
Answer:
130m
Explanation:
You just have to multiply velocity by the time traveled:
100m/s * 1.3s = 130m!
