In a Physics 111 laboratory experiment, a cart with a mass of 0.80 kg and a velocity of 0.50 m/s collides elastically into a sta

faust18 [17]

Elastic collisions are collisions in which both momentum and kinetic energy are conserved. The total system kinetic energy before the collision equals the total system kinetic energy after the collision. We calculate as follows:

m1v1 = m1v1' + m2v2'
0.80(0.50) = (0.80)(0.80-1)/(0.80+1)(0.50) + 1v2'
v2' = 0.11

Hope this helps. Have a nice day.

What is the electric potential difference of 5cm from a point charge of -2.0µc

vodka [1.7K]

Answer:

V = 360 kV

Explanation:

Given that,

Charge, q = -2µC

We need to find the electric potential difference of 5cm from a point charge.

We know that the formula for the electric potential is given by :

$V=\dfrac{kq}{r}\\\\V=\dfrac{9\times 10^9\times 2\times 10^{-6}}{0.05}\\\\V=360000\ V$
