A baseball (m=0.15kg) is thrown with a speed of 30 meters per second at angle of 32 degrees above the horizontal. Neglect air resistance.

a.

What is its momentum at the maximum height?

b.

What is its momentum just before it strikes the ground?

Remember that momentum is a vector, so you need to find the magnitude AND the direction that it is pointing in.

• Hint:
• Solution:part a.
• Solution:part b.
