A sphere made of plastic has a density of 1.00 g/cm3 and a radius of 7.50 cm. It falls through air of density 1.20 kg/m3 and has a drag coefficient of 0.500. What is its terminal speed (in m/s)

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)

Which of the following bonds would be most polar? a. c-i b. c-br c. c-cl d. c-f e. c-o
