(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.)
. The following are speeds and headings displayed on a GPS receiver, (Heading gives the direction of motion based on north = 0°, east = 90°, south = 180°, etc,) In each case, indicate whether the receiver was accelerating during the time between the displays and, if it was, describe in what way the receiver was accelerating.
(a) Initially: 60 mpht 70°; 5 seconds later: .50 mph, 70°.
(b) Initially: .50 mph, 70°; 5 seconds later: 70 mph, 70°.
(c) Initially: 60 mph, 70°; 5 seconds later: 60 mph, 90°.

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.
