Answered by Damon
v down = sqrt (2 g h) = sqrt (2*9.8*5)
= 9.9 m/s

v up = sqrt (2 * 9.8*2)
= 6.26

change in momentu = m delta v = 1(9.9+6.26)
= 16.2 kg m/s

Nice one 👍
Answered by Sagacious
Joyce you recall

V² = U² + 2gh

But here u = 0

You now have

V = √2gh

So you use it to find the first and second velocity
