Aball is thrown from an initial height of 2 meters with an initial upward velocity of 9/ms . the ball's height h (in meters) after t seconds is given by the following. =h+2−9t5t2 find all values of t for which the ball's height is 3 meters. round your answer(s) to the nearest hundredth.

A ball is thrown from an initial height of 2 meters with an initial upward velocity of 9/ms

Balls height

To find all values of t for which the ball's height is 3 meters

We plug in 3 for h and solve for t

Solve for t

Solve using quadratic formula

After simplifying this,

= 0.11898

= 1.68102

the values of t for which the ball's height is 3 meters= 0.12 sec , 1.68 sec

x= 149. 24+7=31. 180-31=149
