Answer 1

-10 times

Question 2

For a projectile shot off a table and allowed to fall to the floor which of the following is true regarding its overall velocity?

Answer 2

-Its initial velocity is less than or equal to its final velocity.

Question 3

For a projectile fired on a constant level surface the max range in the horizontal direction is obtained by firing the projectile at what angle?

Answer 3

-45 degrees.

Question 4

For a projectile fired on a constant level surface its overall velocity is at a minimum when?

Answer 4

-when the projectile is at its max height.

Question 5

What equation given in the manual describes the range(distance traveled in the horizontal direction) for projectile motion.

Answer 5

delta x = initial velocity x cos of angle theta.
