2.48 • A large boulder is ejected vertically upward from a vol- cano with an initial speed of 40.4 m/s. Ignore air resistance. (a) At what time after being ejected is the boulder moving at 20.5 m/s upward? (b) At what time is it moving at 20.5 m/s downward? (c) When is the displacement of the boulder from its initial position zero? (d) When is the velocity of the boulder zero? (e) What are the magnitude and direction of the...

Fleas have remarkable jumping ability. A 0.40 mg flea, jumping straight up, would reach a height of 35 cm if there were no air resistance. In reality, air resistance limits the height to 20 cm . A) What is the flea's kinetic energy as it leaves the ground? K = 1.37×10−3 mJ Part B At its highest point, what fraction of the initial kinetic energy has been converted to potential energy? Express your answer using two significant figures. f =...

A particular cat flea (Ctenocephalides felis) has a mass of 5.0 x 10kg. Like most fleas, this one can jump many times higher than its own height. When jumping, it accelerates from rest through a distance of 0.40 mm, which allows it to reach a launch speed of 1.2 m/s, directed straight up. Use g = 9.8 m/s. [2 points] (a) Assuming constant acceleration, calculate the magnitude of the flea's acceleration while it is accelerating upward. [2 points] (b) For...
