Question:

a. With what speed are pollen grains ejected from a bunch berry flower? See Problem 47 for information.

b. Suppose that 1000 ejected pollen grains slam into the abdomen of a $5.0 g$ bee that is hovering just above the flower. If the collision is perfectly inelastic, what is the bee's speed immediately afterward? Is the bee likely to notice?

Problem 47

The flowers of the bunchbeny plant open with astonishing force and speed, causing the pollen grains to be ejected out of the flower in a mere 0.30 ms at an acceleration of 2.5 × 10⁴ m/s². If the acceleration is constant, what impulse is delivered to a pollen grain with a mass of 1.0 x 10^-7 g?
