Catapulting mushrooms. Certain mushrooms launch their spores by a catapult mechanism. 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 a film grows on the other side.The spore is bent over by the drop’s 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 it is slung off into the air. Typically, the spore reaches a speed of 1.6 m/s in a 5.0 mm launch; its speed is then reduced to zero in 1.0 mm by the air. Using those data and assuming constant accelerations, find the acceleration in terms of g during (a) the launch and (b) the speed reduction.

Question
Catapulting mushrooms.
Certain mushrooms launch
their spores by a catapult mechanism.
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 a film
grows on the other side.The spore is bent over by the drop’s 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 it
is slung off into the air. Typically, the spore reaches a speed of 1.6
m/s in a 5.0 mm launch; its speed is then reduced to zero in 1.0 mm
by the air. Using those data and assuming constant accelerations,
find the acceleration in terms of g during (a) the launch and (b) the
speed reduction.
