Well if the encounter is good then that would be great to write about!!
Answer:

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.
∑F = ma = (90 kg)(1.2 m/s²) = 108 N = 100 N (1 significant digit)
