Answer:
The velocity of the boy and the bicycle is 2.2 m/s.
Explanation:
We have,
Mass of child is 30 kg and the mass of bicycle is 20 kg. The combined momentum of the child and the bicycle is 110 kg-m/s.
It is required to find the velocity of the boy and the bicycle. The momentum of an object is given in terms of mass and its velocity. So,
M is combined mass of child and bicycle
So, the velocity of the boy and the bicycle is 2.2 m/s.
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>
