A 35 kg boy is riding a 65 kg go-cart. He pushes on the gas pedal, causing the cart to accelerate at 5 m/s2. Use the equation F = m × a to find the force exerted by the go-cart’s engine.

Answer:


\boxed {\boxed {\sf 500 \ Newtons }}

Step-by-step explanation:

The equation for force is given:


F=m*a

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.


m= 100 \ kg \\a= 5 \ m/s^2

Substitute the values into the formula.


F=100 \ kg * 5 \ m/s^2

Multiply.


F= 500 \ kg*m/s^2

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


F= 500 \ N

The force exerted by the go cart engine is 500 Newtons.
