A 0.09 kg ball of dough is thrown straight up into the air with an initial speed of 5.5 m/s

Question

(a) Find the momentum of the ball of dough at its maximum height.

(b) Find the momentum of the ball of dough halfway to its maximum height on the way up.

Answer 1

a) the ball has no velocity at the top.

b) You know the KE of the ball at launch. What is the KE half way up? ANS 1/2 the initial.
Then figure v for that KE

Answer 2

Then, don't forget to multiply the velocity by the mass to find the momentum.
