A man pushes a drum of oil 10kg up an incline 0A.if 0A is 5m and AB is 3m.What is the potential energy of the drum at A?
Need more explanation
I don't have any response
150j
Potential energy=mgh
=10*10*3
=300joules
answer it
To find the potential energy of the drum at point A, we need to use the equation:
Potential Energy = Mass × Gravity × Height
Given:
Mass of the drum (m) = 10 kg
Height from point A (h) = 5 m
Now, we need to find the value of Gravity (g). The standard value for acceleration due to gravity is approximately 9.8 m/s².
Using the given values, we can calculate the potential energy of the drum at point A as follows:
Potential Energy at A = Mass × Gravity × Height
Potential Energy at A = 10 kg × 9.8 m/s² × 5 m
Potential Energy at A = 490 J
Therefore, the potential energy of the drum at point A is 490 Joules.
IS AB the height?
If so, the the potential energy at A is mgh=10*9.8*3 joules
