c2.8 p63 PRACTICE!

In Problems 1 through 3, give assignment statements for computing the indicated
values, assuming that the variables have been declared and given appropriate
values. Also assume that the following declarations have been made:

#define g 9.8
#define PI (4*atan(1))       /* more accurate than 3.141593 */

     1.  Velocity computation:

         

     2.  Length contraction:

         

     3.  Distance of the center of gravity from a reference plane in a
	 hollow cylinder sector:

         

In Problems 4 through 6, give the equations that correspond to the assignment statement.

     4.  Electrical oscillation frequency:

         frequency = 1/sqrt(2*pi*c/L);

     5.  Range for a projectile:

         range = (v0*v0/g)*sin(2*theta);

     6.  Speed of a disk at the bottom of an incline:

         v = sqrt(2*g*h/(1 + I/(m*pow(r,2))));
