Answer:
17.8 m/s
Step-by-step explanation:
v = speed at which the golf ball is hit by the golfer = 31 m/s
θ = angle at which the golf ball is launched = 35 degrees
v' = vertical velocity component of the ball
vertical velocity component of the ball is given as
v' = v Sinθ
inserting the values
v' = 31 Sin35
v' = (31) (0.574) Since Sin35 = 0.574
v' = 17.8 m/s
