Answer:
A. Energy = 490 Joules
B. Power = 16.3 Watts
Explanation:
Given the following data;
Mass = 5kg
Height = 10m
Time = 3 seconds
To find the power;
First of all, we would have to determine the energy possessed by the object due to its height (potential energy).
We know that acceleration due to gravity is equal to 9.8m/s²
Energy = mgh
Energy = 5*9.8*10
Energy = 490 Joules
Now, we would find the power;
Power = energy/time
Power = 490/3
Power = 16.3 Watts
