A 25 kg kid is trying to jump into a small boat, which is stationary. The kid jumps with a velocity of 7.5 m/s to the west. However, instead of landing in the boat, he hits the side of the boat, and bounces
off with a velocity of 5.00 m/s to the east. If the boat was 150 kg, what would the boat's velocity be
afterwards?

the correct choice is a .

do not post any more test or exam questions on

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
