Textbook Question

Chapter P.2, Problem 7P

The following passages and associated questions are based on the material of Part II.

Big Air

A new generation of pogo sticks lets a rider bounce more than 2 meters off the ground by using elastic bands to store energy. When the pogo’s plunger hits the ground, the elastic bands stretch as the pogo and rider come to rest. At the low point of the bounce, the stretched bands start to contract, pushing out the plunger and launching the rider into the air. For a total mass of 80 kg (rider plus pogo), a stretch of 0.40 m launches a rider 2.0 m above the starting point.

Chapter P.2, Problem 7P, The following passages and associated questions are based on the material of Part II. Big Air A new

Suppose a much smaller rider (total mass of rider plus pogo of 40 kg) mechanically stretched the elastic bands of the pogo by 0.40 m, then got on the pogo and released the bands. How high would this unwise rider go?

A. 8.0 m

B. 6.0 m

C. 4.0 m

D. 3.0 m

13. After a gust of wind, an orb weaver spider with a mass of 35 g, hanging on a strand of web of length L = .420 m, undergoes simple harmonic motion (SHO) with an amplitude A and period T. If the spider climbs 12.0 cm up the web without perturbing the oscillation otherwise, what is the period of oscillation, in Hz to three significant figures?

15. An object of mass m = 8.10 kg is attached to an ideal spring and allowed to hang in the earth's gravitational field. The spring stretches 23.10 cm before it reaches its equilibrium position. The mass then undergoes simple harmonic motion with an amplitude of 10.5 cm. Calculate the velocity of the mass in m/s at a time t= 1.00s to three significant figures.
