Jogging Jake runs along a train flatcar that moves at the velocities shown. From greatest to least, rank the relative velocities of Jake as seen by an observer on the ground. (Call the direction to the right positive.)

To rank: The relative velocities of person J , from greatest to least, as seen by an observer on the ground.
Answer to Problem 20A
D> C > A > B
Explanation of Solution
Given:
The given figure representing the velocity of person J at different locations is shown below.
Right direction is considered positive.
Formula used:
Relative velocity with respect to the observer on the ground is the vector sum of person J speed and the train flatcar.
⇀vo=→vt+→vJ
Calculation:
Calculate the relative velocity at each position if right direction is considered positive.
For case A,
→vo=8−4=4m/s
For case B,
→vo=−10+6=−4m/s
For case C,
→vo=6+4=10m/s
For case D,
→vo=18−6=12m/s
At D, relative velocity is maximum and at B, relative velocity is minimum.
Conclusion:
Therefore, the ranking of relative velocities is D> C > A > B.

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?arrow_forward

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.arrow_forwardplease solve and answer the question correctly. Thank you!!arrow_forward18arrow_forward
- 1. Some 1800 years ago Roman soldiers effectively used slings as deadly weapons. The length of these slings averaged about 81 cm and the lead shot that they used weighed about 30 grams. If in the wind up to a release, the shot rotated around the Roman slinger with a period of .14 seconds. Find the maximum acceleration of the shot before being released in m/s^2 and report it to two significant figures.arrow_forward16arrow_forward11. A small charged plastic ball is vertically above another charged small ball in a frictionless test tube as shown in the figure. The balls are in equilibrium at a distance d= 2.0 cm apart. If the charge on one ball is tripled, find the new equilibrium distance between the balls in cm and report it to the proper number of significant figures.arrow_forward
