A 27.5 kg ball is thrown at an angle of 22.7° above the horizontal off of a building such that its initial potential energy is 423 J, and the initial kinetic energy is 347 J.

What will be the speed of the ball at the moment before it hits the ground?

*Remember to use the conservation of Energy!

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
