The incline is frictionless, this means we can use the conservation of energy: the initial kinetic energy of the block
is converted into gravitational potential energy
where h is the height reached by the block as it stops. By equalizing the two formulas, we get
However, this is the maximum height reached by the block. The distance along the surface of the plane is given by:
I'm guessing D. toothpick, but i might be wrong.
Answer;
how fast or slow something is done.
Explanation;
The term rate refers to how fast or slow something is done. For example; a higher rate shows how fast something is being done or is taking lace, lower rate shows how slow something is being done.
In other words it is a quantity measured with respect to another measured quantity; for instance; a rate of speed of 60 miles per hour.
Answer:
The final energy of the system is 168 J
Explanation:
Heat energy released to the surroundings,
Work done, W = 222 J
The initial internal energy,
The change in internal energy is given by the formula,
The final energy of the system is 168 J
