5. Click on the Projectile Motion (baseball) simulation below. Click on the player to activate a throw. Your target is first base, which is 80 m from the thrower. After experimenting with this simulation several times, answer the following questions.

Lab 5: Projectile Motion (core)

http://www.mhhe.com/physsci/physical/jones/graphics/jones2001phys_s/scripts/core_lib/projectile_motion/index.html

a. At what projection angle does a throw reach first base in the shortest time?

b. At what projection angle can a ball be thrown and reach first base with the least projection speed?

c. What are the answers to questions a and b if the player is on the moon?
Angle for throw of shortest time?

Angle for throw with least speed?

Explain why these are different than on earth:

d. What are the answers to questions a and b if the player is on Mars?
Angle for throw of shortest time?

Angle for throw with least speed?

Explain why these are different than on earth:
