. 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°.

Question 2 I am driving down the street at 11.2 mi/h and suddenly I see a squirrel. I slam on the brakes in 0.62 seconds to avoid hitting the squirrel. Luckily, he got away. With what force in kiloNewtons did the 307 kg car come to a stop? Round to the nearest whole hundredth, and enter the magnitude, which does not include negatives. Next Newton's Law....docx Newton's Law....docx Jillian Wagner...docx Jillian Wagner...docxarrow_forwardI was able to understand the attached problem and have the answer now for mu. So the equation I have is v=150e-6.0788 x My question, then, is how do we find the TIME to slow the sled to 15 mi/hr ? The answer is supposed to be 35.533 seconds, but I don't know how to get that.
