Answer:
power will three times decrease (one-third)
Explanation:
P = W / t
thus when work is constant, power is inversely proportional to time
so, when time is tripled, power is decreased to one-third

The rule to get the average speed is as follows:
average speed = average distance / average time
We are given that:
distance = 250 m
time = 110 sec
Substitute with the givens in the above equation to get the average speed as follows:
average speed = 250/110 = 25/11 meters/sec
It looks correct, but that graph only shows position and time?
So this form of energy is gravitational potential, which is defined as mass*height*gravity so if we use gravity as 10 m/s^2 to keep it simple we can do 150kg*10m*10m/s^2 and we get a total of 15,000 joules
