The flowers of the bunchberry plant open with astonishing force and speed, causing the pollen grains to be ejected out of the flower in a mere .3 ms at an acceleration of 2.5 * 104 m/s^2. The grains are ejected from the flower at 7.5 m/s. - Suppose that 1000 pollen grains slam into the abdomen of a 5.0 g bee that is hovering just above the flower. The grain's mass is 1.0 * 10-7 g. If the collision is inelastic, what is the bee's speed immediately afterward?
