Answer:
Explanation:
The linear momentum during this collision must be conserved, which means that momentum before and after the collision must be the same.
We have a big defensive lineman of mass and velocity going in what we will call the positive direction, and a wide receiver of mass and velocity which we don't know. Since the collision is head on, momentum before the collision will be
After the collision, the receiver drops the lineman in his tracks, which means they come to a stop, so the momentum is null, and since this momentum must be equal to the one before the collision we have:
Which means:
So for we have:
where the negative sign indicates its opposite to our positive direction (of the big defensive lineman).
The initial acceleration of the wishbone is 13.1 m/s².

Acceleration:</h3>
This can be defined as the rate of change of velocity. The S.I unit of acceleration is m/s²
To calculate the acceleration of the wishbone, we use the formula below.
⇒ Formula:
- F' = ma........................... equation 1
⇒ Where:
- F' = Net force between Kevin and Gamal
- m = mass of the wishbone
- a = acceleration of the wishbone
⇒ make a the subject of the equation
- a = F'/m....................... Equation 2
From the question,
⇒ Given:
- F' = 0.17 N
- m = 13 g = 0.013 kg
⇒ Substitute these values into equation 2.
- a = 0.17/0.013
- a = 13.1 m/s²
Hence, The initial acceleration of the wishbone is 13.1 m/s².

Answer:
D. Nuclear fusion
Explanation:
Nuclear fusion is a nuclear reaction where nuclei of atoms( one of low atomic number and another with a higher atomic number) join together to form a much bigger nucleus and release a lot of energy.In the sun, which is a star of course, where light is released,hydrogen is converted to helium and the process releases massive energy into space in form of heat and light.
