hhmmmmmhmmmm hmhmmmm hmmm yeah i got nothing
Explanation:
Answer
given,
before collision
mass of car A = m_a = 1300 kg
velocity of car A = v_a = 35 mph
mass of car B = m_b= 1000 kg
velocity of car B = v_b = 25 mph
after collision
V_a = 30 mph
V_b = 31.5 mph
Initial momentum
final momentum
here initial momentum is equal to the final momentum of the car.
hence, momentum is conserved in the collision.
Answer:
d) KEe = KEp
Explanation:
According to the law of conservation of energy, the electric potential energy is converted into the kinetic energy of the particle:
Here, q is the particle's charge and V is the potential difference.
The charge of the electron is -e. So:
The charge of the proton is e. So:
So
