Explanation:
Given:
- mass of the ball thrown up,
- initial velocity of the ball thrown up,
- height above the ground from where the ball is thrown up,
a)
Maximum height attained by the ball above the roof level can be given by the equation of motion.
As,
where:
final velocity at the top height of the upward motion
acceleration due to gravity
height of the ball above the roof
Now,
Therefore total height above the ground:
b)
Now we find the time taken in raching the height :
final velocity at the top of the motion
So,
Now the time taken in coming down to the ground from the top height:
where:
is the initial velocity of the ball in course of coming down to ground from the top
Here the direction acceleration due to gravity is same as that of motion so we are taking them positively.
Therefore the total time taken in by the ball to hit the ground after it begins its motion:
Answer:
Explanation:
Given
Temperature of gas at First stage
Pressure of gas at First stage
Volume Occupies
If the Pressure and Temperature at second stage is
Using ideal gas Equation
where P=Pressure
V=volume
R=Universal Gas constant
T=Temperature
n=no of moles
as n and R is constant therefore
thus
