Answer:
The kinetic energy is 
Explanation:
From the question we are told that
The potential difference is 
The potential energy of the end is mathematically represented as

q is the charge on an electron with a constant value of 
substituting values


Now from the law of energy conservation
The 
Where
is the potential energy at the end
So

The negative sign is not includes because kinetic energy can not be negative
I believe that is true. Anaerobic means without (much) Oxygen. This usually builds up lactic acid in muscles.
Answer:
a) 8.61 m/s, b) 5.73 m
Explanation:
a) During the collision, momentum is conserved.
mv = (m + M) V
(12.5 g) (86.4 m/s) = (12.5 g + 113 g) V
V = 8.61 m/s
b) After the collision, energy is conserved.
Kinetic energy = Work done by friction
1/2 (m + M) V² = F d
1/2 (m + M) V² = N μk d
1/2 (m + M) V² = (m + M) g μk d
1/2 V² = g μk d
d = V² / (2g μk)
d = (8.61 m/s)² / (2 × 9.8 m/s² × 0.659)
d = 5.73 m
Notice we used the kinetic coefficient of friction. That's the friction when an object is moving. The static coefficient of friction is the friction on a stationary object. Since the bullet/block combination is sliding across the surface, we use the kinetic coefficient.
Answer:
Acceleration occurs when an object changes its VELOCITY or DIRECTION or both
