Question

You decide to play a trick on your friend using a giant water balloon as shown in the figure attached below. The balloon is dropped (no initial velocity) from a height of 42.79 meters. At the exact moment, you drop the balloon your friend throws a rock straight up to strike and burst the balloon before it lands. We will take the rock to be thrown with an initial velocity of 108 km/hr from an initial height of zero.

Convert the rock's initial velocity into proper units. v0(rock) = ? meters/second

Write an equation for the y of the balloon at any time. yballoon(t) =

Write an equation for the y of the rock at any time. yrock(t) =

Determine the time at which the rock and balloon collide. tcollision = ? seconds.

NOTE: The equations you input should have all numbers, except for the letter t. Examples of correct format (but not the right answers):
