A 59 kg skier starts from rest at height H = 25 m above the end of a ski-jump ramp (see the figure). As the skier leaves the ramp, his velocity makes an angle of θ = 20° with the horizontal. ?
Neglect the effects of air resistance and assume the ramp is frictionless. (a) What is the maximum height h of his jump above the end of the ramp? (b) If he increased his weight by putting on a 10 kg backpack, what would h be?

(a)
(b)
There will be no effect.
Explanation:
To find his velocity at the end of the ramp we can use the conservation of energy:
Potential energy = kinetic energy
Now we can get
(b)
You can see that
