Answer:
v = 30.39 m/s
Explanation:
given,
mass of glider,M = 680 Kg
mass of the skydiver, m = 68 Kg
horizontal velocity,V = 30 m/s
when skydiver releases, velocity,v = 30 m/s
velocity if the glider,v' = ?
use the conservation of momentum
M V = m' v' + m v
m' = 680-68 = 612 Kg
680 x 30 = 612 x v + 60 x 30
612 v = 18600
v = 30.39 m/s
since the skydiver's speed will be the same as before release
The glider should continue to travel at 30.39 m/s since there are no external forces acting on it
Hello!
The balloon explodes, because the pressure builds up inside and the air want to expand. Letter a)

If you mean nuclear, fission is a radioactive isotope losing protons or "radioactive decay"
whereas nuclear fusion is where 2 atoms hit each other and combine,
like on the sun where hydrogen hits each other and makes helium.
