I. Free Fall Motion

A mass m = 544 g is thrown straight up with an initial speed of 3.50 m/s from a height of h = 2.50 m Neglecting a drag force,

determine:

1. The acceleration of the object while it moves up.

2. The acceleration of the object at the highest point.

3. The maximum height that the mass reaches.

4. The total time the object is in the air if it is allowed to freely fall to the ground.

5. The speed the mass has just before it hits the ground.

6. The speed of the mass at the highest point.

7. The speed of the mass at h = 2.50 m on its return trip down.

My prof. was very vague on our equations to use

from what I understand I was able to get

1. Acceleration while moving up = -9.81m/s^2

2. Acceleration = 0

3.

4. .357s

feel free to suggest relevant equations for these problems.
