Someone stuck a piece of chewing gum on the outer edge of a blade on a ceiling fan. The radius (r) of where the gum is from the center of the spinning fan is 0.60m. The period (T) that it takes for the blade to complete one revolution is 0.25seconds on its slowest speed setting. If we estimate the piece of chewed gum to have a mass (m) of 0.0026Kg, then how much centripetal Force (Fc) is on the gum when the fan is spinning at this speed?

A33.1 g copper object is launched from a 1.5 m 30° steel incline positioned on the floor by being pulled up a string attached to a 50.0 g mass suspended vertically over a pulley. the object is projected towards a glass table where it lands when it is at the point along its trajectory with the lowest speed. it comes to a halt when it clears the opposite edge of the table. it then falls and lands on 9 physics texts each 5 cm thick that are stacked on the floor on the opposite side of the table. assume that the table does not have a ledge and the rectangular object experiences 0.05 n of air resistance as it falls towards the books. how far and how long did the object travel and how fast does it hit the books. assume that at the moment the copper object leaves the incline, the massless string and ideal pulley break off

Two students, each riding bicycles, start from the same apartment building and ride to the same building on campus, but each takes a different route. the first student rides 1100 m due east and then turns due north and travels another 1430 m before arriving at the destination. the second student heads due north for 1930 m and then turns and heads directly toward the destination.at the turning point, how far is the second student from the destination?

How does an observation about an object differ from an inference about that object
