A quarterback throws a football with an angle of elevation 40° and speed 80 ft/s. Find the horizontal and vertical components of the velocity vector. (Round your answers to one decimal place.)

Answer 1

V_x= V Cos ( ∅ ) which is the horizontal component of velocity

V_y= V Sin ( ∅ ) vertical component of the velocity

V_x= 80 Cos (40) = 61.28 = 61.3 ft/ s rounded to one decimal place

V_y = 80 Sin ( 40 ) = 51.42 = 51.4 ft/ s rounded to one decimal place

V = 61.3 i + 51.4 j = < 61.3, 51.4 >
