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

(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.

• science/physics -

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

• science/physics -

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