1.Daw a graph between the range and the maximum height and find the ratio of hmax to Rmax.Based on the initial vertical velocity, find the time 't'it takes for the projectile to reach its maximum height.Based on the short range initial speed and the various launch angle calculate the initial vertical velocity and the initial horizontal velocity for each launch angle.Place the pad at the same height as the end of the projectile launcher.Place the Time-of-Flight Pad at the horizontal distance you calculated for the range.2.3.4.5.Arrange the data in table 2.6.

1. 
   

   Based on the short range initial speed and the various launch angle calculate the initial vertical velocity and the initial horizontal velocity for each launch angle.

   
   


2. 
   

   Based on the initial vertical velocity, find the time 't'it takes for the projectile to reach its maximum height. Multiply the time by 2 to get the total time of flight or directly note down the time of flight from the data logger.

   
   


3. 
   

   From the data of table 1, draw a graph of the range and the angle and find the angle for the maximum range.

   
   


4. 
   

   Place the Time-of-Flight Pad at the horizontal distance you calculated for the range. Place the pad at the same height as the end of the projectile launcher.

   
   


5. 
   

   Reload the launcher and set it to the short-range position. Shoot the ball and observe how close it lands to the spot you predicted. Arrange the data in table 2.
