A 65 kg skateboarder is moving to the right at 6.8 m/s when a 52 kg skateboarder moving at 12 m/s bumps into her from behind. The 65 kg skateboard goes flying off his skateboard at 9.3 m/s. What is the final velocity of the 52 kg skateboarder?

28. evolution

29. environment, survive, offspring  

explanation:

answer: i think he can see forward ten seconds and move forward ten seconds but giorno can undo his actions with ger.

explanation:

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
