Explanation:
Maximum height of the pumpkin, 
Initial speed, v = 22 m/s
We need to find the angle with which the pumpkin is fired. the maximum height of the projectile is given by :
On rearranging the above equation, to find the angle as :
So, the angle with which the pumpkin is fired is 39.49 degrees. Hence, this is the required solution.
No. You cannot rule out the battery even after the open circuit voltage measurement. The open-circuit voltage may not have changed but the battery's internal resistance may have greatly increased.
