if a ball is dropped from a height of 19.6m, what is the velocity with which the ball hits the ground?

A spring of negligible mass and force constant k = 400 N/m is hung vertically, and a 0.240 kg pan is suspended from its lower end. A butcher drops a 2.4 kg steak onto the pan from a height of 0.40 m.

1. A man walks 30 m south, 60 m west, 25 m north and 40 m west. A) What is the total distance walked by the man? B) Draw the path the man follows. C) What is the man's displacement (R & 0) ?

Why does a black ball appear black in white light?

A package falls out of an airplane that is flying in a straight line at a constant altitude and speed. If you ignore air resistance, what would be the path of the package as observed by the pilot? As observed by a person on the ground?

The captain told the passengers that the plane is flying at 450 miles per hour this information describes the plane Velocity Speed Acceleration Direction

How do you get over a break up? (I know this has nothing to do with school work but I really need some advice.)

Suppose you have a hypothesis you believe to be correct what should you do to make you become a theory A. Write a letter to the noble prize committee B. Do the same experiment over and over again C.

What method of heat transfer does heat energy use to reach earth from the sun?

What is the spring constant (in n/m) of a spring that stores 100 J of elastic potential energy when it is stretched 5 m?

Assuming 100% efficient energy conversion, how much water stored behind a 50cm high hydroelectric dam would be required to charge a 50 ampere-minute 12 volt battery with 600j of energy stored in it
