Randy throws a tennis ball horizonally to hit a wall 20 m away. If the ball hits the wall 1.5s after it is thrown, what is the horizontal component of the balls velocity?
To find the horizontal component of the ball's velocity, we need to determine the speed at which the ball is traveling horizontally. We can use the formula for horizontal distance traveled:
horizontal distance = horizontal velocity * time
In this case, we know that the horizontal distance is 20 m and the time is 1.5 s. Rearranging the formula, we can solve for the horizontal velocity:
horizontal velocity = horizontal distance / time
Plugging in the given values:
horizontal velocity = 20 m / 1.5 s
Simplifying the division, we get:
horizontal velocity = 13.33 m/s
Therefore, the horizontal component of the ball's velocity is 13.33 m/s.
