Tarzan swings on a 30.0 m long vine initially inclined at an angle of 37.0 with the vertical. What is his speed at the bottom of the swing if he does the following: a. starts from rest
b. pushes off with a speed of 4.00 m/s

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
