Question 1
Procedure: Keep the initial velocity fixed at 50 m/s. Perform the experiment for each of the following angles:
- 15 degrees
- 30 degrees
- 45 degrees
- 60 degrees
- 75 degrees
Record in table 1:
- The maximum horizontal distance (Range) traveled by the projectile at various angles
- The total time of flight at various angles
- The maximum height attained

Observe and Analyze:
- What angle produces the maximum range? Why?
- What angle produces the maximum height? Why?
- Are there angles which produce the same range? If so, how would you explain this?
Question 2
Procedure: Set the angle to 45 degrees. Perform the experiment with the following initial velocities.
- 30 m/s
- 40 m/s
- 50 m/s
- 60 m/s
Record in Table 2: The horizontal and vertical components of the velocity and the ranges for each of the velocities.

Observe and Analyze:
- As the velocity is increased what happens to the Range?
- Using the initial horizontal and vertical velocities from your table, verify mathematically that the range is correct for the initial speed of 60 m/s.
