as power =mgh/time
so when h=0
power will be also 0
so when body is just projected or at the end of projectile power is 0
so when h=0
power will be also 0

Answer:
Explanation:Acceleration = (Final velocity - Initial velocity )/ Time
Acceleration = (0 - 50) / 5
Acceleration = -50 / 5
Acceleration = -10m/s^2
