How long is rock in air from the instant it is released

A rock is tossed straight up with a speed of 20m/s when it returns it falls into a hole 10m deep.

What is the rock's velocity as it hits the bottom of the hole ?

How long is the rock in the air from the instant it is released until it hits the bottom of the hole ?

Q : Find the energy transferred by helium

A 2.20 mol sample of helium gas initially at 300 K and 0.400 atm is compressed isothermally to 1.30 atm. Note that the helium behaves as an ideal gas. Find the energy transferred by helium.

Q : Why you still use the sample for your analysis

The equation, A = a*b*c becomes nonlinear at high concentrations of the absorbing substance. Suppose you prepare a solution with a very high absorbance that is suspect in not following the linear relationship.
