Based on the diagram, what is the initial horizontal velocity of the ball (in m/s)? m x = Correct! m x = 120 cos ( 0.7 ) 91.781 . Based on the diagram, what is the initial vertical velocity of the ball (in m/s)? m y = Correct! m y = 120 sin ( 0.7 ) 77.306 . LicenseQuestion 14. Points possible: 3 Unlimited attempts.

Score in gradebook: 3 Message instructor about this question Once we know the ball's initial horizontal and vertical velocity, we can say a lot about the ball's physical path. Let's let t represent the number of seconds since the ball was launched. Score on last attempt: 3 out of 3 Score in gradebook: 3 out of 3 In this situation, the formula y = 32 t 2 + m y t gives the ball's height above the ground in meters, y , in terms of the number of seconds t since the ball was launched. Rewrite the formula above by replacing m y with its numerical value. (You should have found this value in the previous question.) y = Correct. Since m y 77.3061
