a 100kg ball is thrown vertically upwards with an initial velocity of 15m.s, whats its momentum halfway to its maximum height?

100 kg is a BIG ball, 100 grams is roughly a small baseball. A standard baseball is 145 g.

v² = v₀² + 2as

The maximum height is

0² = 15² + 2(-9.8)s

s = 11.48 m

s/2 = 5.74 m

v² = 15² + 2(-9.8)5.74

v² = 112.5

v = 10.6 m/s

p = mv

p = 100(10.6)

p = 1060 kg•m/s

divide this result by a thousand if the mass was actually 100 g

I hope this helped.
