b cos K60 at an angle of 13 2 points The range R of shot put

(b) cos K-60 at an angle of 13. (2 points) The range R of shot put thrown with an velocity of vo ft/sec range of the initial a the force of gravity. Find the where g 32 ft/sec2 is 6 is given by R n angles of shot put if it is thrown with vo 12 ft/sec at (a) 30° (b) 45 of n triangle with sides of length 7 and 9 meters and included angle (c) 70°

Solution

R = vo^2 sin ( 2theta) / g

range of shot put if theta = a) 30 degrees

R = 12^2 sin ( 2 * 30) / 32 = 3.897

b) when theta = 45 degrees

R = 12^2 sin ( 2*45) / 32 = 4.5

c) when theta = 70 degrees

R = 12^2 sin ( 2*70) / 32 = 2.892
