You should always show your work and/or explain your reasoning and you should always show equations in symbols first before putting in any numbers and include the units throughout your calculations. 1) A hot air balloon has a vertical speed of +5.0m/s when a passenger releases a small rock over the side at a height of 120m above the ground. a) What is the velocity of the rock when it is released? Show your work and/or explain your reasoning. b) Determine the velocity of the rock just before it hits the ground. Show your work. Vf2 -V: How long is the rock in the air? Show your work.
