Q1. A Ford Mustang can accelerate from 0 to 60 in a time of 5.4. A Mini Cooper isn't capable of such a rapid start, but it can turn in a very small circle 35 in diameter. How fast would you need to drive the Mini Cooper in this tight circle to match the magnitude of Mustang's acceleration?
Q2. A 53 kg skier skis directly down a frictionless slope angled at 12° to horizontal. Choose the positive direction of the x axis to be downhill along the slope. A wind force with component Fx acts on the skier. What is Fx if the magnitude of the skier's velocity is (a) constant, (b) increasing at the rate of 1.2 m/s2, and (c) increasing at the rate of 2.5 m/s2. Use g=9.81 m/s2.
A conducting rectangular loop of mass M, resistance R, and dimensions w by l falls from rest into a magnetic field. All through the time interval before the top edge of the loop reaches the field, the loop approaches a terminal speed vT.
A person with a mass of 103 kg is standing on a scale that reads weight in newtons inside of an elevator. If the elevator accelerates upward at 3.2 m/s2, what does the scale read.
The radar system at an airport broadcasts 15 GHz with 150 kW. An approaching airplane with a 34 m^2 cross section is 24km away. Assume that the radar broadcasts uniformly in all directions and that the airplane scatters microwaves uniformly in all di..
A hydrometer is used to measure the specific gravity of liquids. For a sure liquid a hydrometer reading indicates a specific gravity of 1.15. What is the liquid's density and specific weight? State the answer in SI units.
