Answer: P = 5.44 KW
Explanation:
The formula for calculating power is expressed as
P = VI
where
v is the voltage
I is the current
From the information given,
v = 320
I = 17
Thus,
P = 320 x 17 = 5440 W
We would convert it to KW by dividing by 1000. It becomes
P = 5440/1000
P = 5.44 KW
If there’s no friction acting on either object then they will both be falling at a speed of 9.8m/s which is the force of gravity!
Answer:
Explanation:
When I hear "transformation of energy from one form to another", I think of the system exchanging energy with its surroundings. A transformation of energy simply means the system contains a different type of energy than it previously did. One example I can give is a ball. A ball at the top of a hill has a maximum potential energy. If given the chance to roll, it will go to a minimum state of potential. This will convert all of the potential energy into pure kinetic energy, once it reaches the bottom of the hill of course.
Potential equals kenecric at the bottom so potential would also increas
F = 500N
S = 5m
T = 1.2s
----------------------------------
P = ?
We can use formula P = F * V, just because it was a smooth slide we can assume that average speed was V = S/T = 5 / 1.2 = 50/12
So the final answer would be:
P = F * V = 500 * 50/12
Are you sure those are correct numbers? The answer don't look nice :D
