Answer:
Force, F = 44 N
Explanation:
Given that,
Initial speed of the football, u = 0
Final speed, v = 15 m/s
The time of contact of the ball, t = 0.15 s
The mass of football, m = 0.44 kg
We need to find the average force exerted on the ball. It is given by the formula as :

So, the average force exerted on the ball is 44 N. Hence, this is the required solution.
I think the answer should be that, Kinetic energy is contained in a moving object, while potential energy exists in a stored form.
Answer:
The velocity of the recoil is 
Explanation:
Kinetic Energy

The mass of th gun is the both mass the shotgun and the arm shoulder combination

The velocity is negative because is in opposite direction of the bullet
Answer:
Explanation:
a ) 12.0 lbs - mass
b ) .34 g - mass
c ) 120 kg - mass
As lbs , g and kg are units of mass , these things represent mass . lbs is FPS unit of mass and kg is SI unit . g is CGS unit of force .
d ) 1600 kN It represents force because kN or kilonewton is unit of force .
e ) it represents , length or distance because m or metre is unit of length .
f ) 411 cm It represents length or distance because cm is smaller unit of length
g ) 899 MN or million newton . Like d ) It also represents force . Million newton is higher unit of force .
