Question

Mushrooms launch their spores using a catapult mechanism designed by nature. As water condenses from the air onto a spore that is attached to the mushroom, a drop grows on one side of the spore and film grows on the other side. The spore is bent over by the drops weight, but when the film reaches the drop, the drop's water suddenly spreads into the film and the spore springs upward so rapidly that is slung off into the air. The spore reaches a speed of 1.6m/s over a distance of 5 x10 m. Hint: I know this sounds hard when put in a real life situation but it's really just a 1D kinematics problem. Usea laundry list 1. a. What is spore's acceleration? b. If lg is 98 m/s how many g's does the spore experience?

Explanation / Answer

a)

Using 3rd equation of motion

a= (v^2)/(2d)= 1.6^2/(2*5*10^-6)= 256000 m/s^2

=======

b)

a= 26122.4 g

=======

Comment in case any doubt.. good luck
