Answer:
Due to energy loss while collision ball will not reach to same height while if there is no energy loss then in that case ball will reach to same height
Explanation:
As we know that initially ball is held at height h = 40 cm
So here we can say that kinetic energy of the ball is zero and potential energy is given as
now when strike with the ground then its its fraction of kinetic energy is lost in form of other energies
So the ball will left rebound with smaller energy and hence it will reach to height less than the initial height
While if we assume that there is no energy loss during collision then in that case ball will reach to same height again

Explanation:
The top of the trajectory is the point where it changes from rising to falling. At that exact instant, its vertical speed is zero.
As the water boils at a certain temperature, phase change happen without change in its temperature. The heat associated is called the latent heat of vaporization. We obtain the heat required by multiplying the mass of the water to the latent heat of vaporization.
Heat = 0.018 x <span>2.3 x 10000000 = 41400 J</span>
If you fly at 100 miles per hour for a time of 2 hours and 30 minutes you will be a: 250 miles far
The formula and procedure we will use to solve this exercise is:
x = v * t
Where:
- x = distance
- t = time
- v = velocity
Information about the problem:
- v = 100 miles/h
- t = 2,5 h
- x=?
Applying the distance formula we have that:
x = v * t
x= 100 miles/h * 2,5 h
x = 250 miles
<h3>What is velocity?</h3>
It is a physical quantity that indicates the displacement of a mobile per unit of time, it is expressed in units of distance per time, for example (miles/h, km/h).
