Question 2

A uniform solid sphere of mass 1.5 kg and diameter 30.0 cm starts from rest and rolls without slipping down a 35 incline that is 7.0 m long.
 
  (a) Calculate the linear speed of the center of the sphere when it reaches the bottom of the incline.
  (b) Determine the angular speed of the sphere about its center at the bottom of the incline.
  (c) Through what angle (in radians) does this sphere turn as it rolls down the incline?
  (d) Does the linear speed in (a) depend on the radius or mass of the sphere? Does the angular speed in (b) depend on the radius or mass of the sphere?

Answer to Question 1

C

Answer to Question 2

(a) 7.5 m/s (b) 50 rad/s (c) 47 rad
(d) The linear speed depends on neither the radius nor the mass of the sphere. The angular speed depends on the radius of the sphere.

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt. For the upper point of his scale, he used 96°, which he measured as normal human body temperature (we know it to be 98.6° today because of more accurate thermometers).
