Potential energy, is energy due to its position.
Given: Mass m = 40 Kg; Height h = 50 m
Required: Potential energy P.E = ?
Formula: P.E = mgh P.E = (40 Kg)(9.8 m/s²)(50 m)
P.E = 19,600 J
Answer: An aspect of the event of various types of balls bouncing off the same floor, being matter is that all the balls consist of matter. They all occupy space and have a form of energy when moved by a force, such as a person. And for energy, like I just said, when they bounce they create energy as they bounce up and down, so if the ball were to hit some other object, it would have an impact on the still object.
The combination of the material properties of a ball (surface textures, actual materials, amount of air, hardness/ softness, and so on) affects the height of its bounce.
Hope this helps.......... Stay safe and have a Merry Christmas!!!!!!!!!! :D
Explanation:
Answer:
Explanation:
Car is 25 m long . worker moves at speed 3.0 m/s with respect to the car
Time taken to reach the other end
= 25 / 3 = 8.333 s
Displacement of flatcar during this period
= 7 x 8.333
= 58.33 m
Answer:
Explanation:
d = Slit separation = 0.11 mm
= Angle = 
m = Order = 2
= Wavelength
We have the relation
The wavelength of the light is .
