Set up the problem with the conversion rates as fractions where when you multiply the units cancel out leaving the desired units behind.
I’m pretty sure 14 is mutations
The horizontal component of the velocity of the ball is calculated by multiplying the speed by the cosine of the given angle.
x-component of speed = (31 m/s)(cos 35°)
= 25.39 m/s
Thus, the horizontal velocity component of the ball is 25.39 m/s.
