The balloon is dropped (no initial velocity) from a height of 43.24 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.
You decide to play a trick on your friend using a giant water balloon as shown in the figure below.
The balloon is dropped (no initial velocity) from a height of 43.24 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.
