Answer:
option B.
Explanation:
The correct answer is option B.
when the ball drops, the velocity of the ball before the collision is v
After the collision, the velocity of the ball is the same but in the opposite direction.
Impulse delivered to the ball and the floor, in this case, is not zero.
The magnitude of the momentum remains the same but the direction of the ball changes.
Answer: 0j
Explanation:
At that point potential energy is zero and kinetic energy is maximum.. P. E=mgh=0
Im not really sure about this im stuck to
Answer:
Explanation:
From the question we are told that
Distance b/w plate 
P_1 Potential at 7.35 
Generally the equation for electric field at a distance is mathematically given as
F=ma
m=F/a=95/0.8= 118.75kg
your friend is pretty heavy XD
