Momentum = mass (kg) * velocity (m/s)
The bullets momentum is 0.05 * 500 = 25
25/0.25 = 100
The ball would travel at 100 m/s.
Answer:
The football is 100 m/s fast
Explanation:
Momentum is the product of the mass of a body and it velocity. Momentum is a vector quantity . Meaning it has both Magnitude and direction. Momentum is the mass of a body in motion. Mathematically,
Momentum = mass × velocity
p = m × v
To calculate how fast the football traveled one needs to calculate for the momentum of the bullet.
Momentum of the bullet = mass × velocity
Momentum of the bullet = 0.05 × 500
Momentum of the bullet = 25 kg m/s
Since the momentum of the bullet is equal to the momentum of the football
Momentum of the football = mass × velocity
How fast means calculate the speed which is the velocity
Velocity = Momentum of the bullet/mass
Velocity = 25/0.25
Velocity = 100 m/s
