After catching the ball, sarah throws it back to julie. however, sarah throws it too hard so it is over julie's head when it reaches julie's horizontal position. assume the ball leaves sarah's hand a distance 1.5 meters above the ground, reaches a maximum height of 8 m above the ground, and takes 1.619 s to get directly over julie's head. what is the speed of the ball when it leaves sarah's hand?

Vo=20.2m/s

Explanation:

We can calculate both components of initial velocity and the use them to calculate the speed as

From the vertical movement to the maximum height:

 since

Now, from the horizontal movement, also to the point of maximum height:

 Solving for

Finally we calculate the magnitude of the new vector:

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
