An object with a mass of 50.0 kg moves with a velocity of 11.2 m/s and an event occurs whereby it transfers
1,539 J of energy to another object as work.
What is the new velocity of the object after the event?

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

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?

Photons with the highest energy have the longest period
