A child kicks a ball with an initial velocity of 8.5 meters per second at an angle of 35.00 degrees above the horizontal. The ball has an initial vertical velocity of 4.9 meters per second and a total time of flight of 1.0 second. The horizontal component of the ball's initial velocity is approximately

6.96 m/s

Explanation:

Horizontal component = V cos α

V= initial velocity of the ball= 8.5 m/s

α = 35°

Horizontal component = 8.5 cos35 = 6.96 m/s

Therefore, the horizontal component of the balls initial velocity is 6.96 m/s
