Problem 5: A meter-stick is moving with a speed of 0.7 c relative to the Earth. What is the stick's length as measured by an observer on Earth if the stick is parallel to its velocity v? What is the stick's length as measured by the observer on Earth if the stick is making an angle of 50° with its velocity v?
Part A Relative to the frame of the observer making the measurement, at what speed parallel to its length is the length of a meterstick 60 cm? O 0.50C O 0.700 O 0.800 O O OO 0.600 0.900
A boat crossing a wide river moves with a speed of 17.0 km/h relative to the water. The water in the river has a steady speed of 6.00 km/h due north relative to the earth. 1) What is the angle made between the velocity of the boat relative to the observer and the west direction? 2) At what angle against the steam must the boat be headed with respect to the west direction in order for it to proceed west...
A boat crossing a wide river moves with a speed of 18.0 km/h relative to the water. The water in the river has a steady speed of 8.00 km/h due east relative to the earth. a) If the boat heads due south, determine the speed of the boat relative to an observer standing on the shore. km/h 9. b) What is the angle made between the velocity of the boat relative to the observer and the south direction? 10. c)...
8. A student rolls a marble alongside a meterstick to measure
its velocity. At t1 = -2.5 s, its position is x1 = 4.3 cm, and at
t2 = 4.5 s it is at x2 = 18.5 cm. Determine its average velocity
during this time interval.
9. The position of a ball rolling along a straight line is given by
? = 1.8−3.6? +1.5?2, where x is in meters and t is in seconds.
Determine the average velocity of the...
A rectangular painting is 123 cm wide and 85.0 cm high, as indicated in the figure(Figure 1). At what speed, v, must the painting move parallel to its width if it is to appear to be square?
A parallel-plate capacitor is
made from two aluminum-foil sheets, each 6.5 cm wide and 6.3 m
long. Between the sheets is a Teflon strip of the same width and
length that is 3.4×10−2 mm thick. What is the capacitance of this
capacitor? (The dielectric constant of Teflon is 2.1.) Answer tried
was incorrect.

3. (6 marks) A rod of length L'-4m is moving in frame y s S' with respect to a stationary observer in frame S. The rod makes an angle e' 60 to the direction of travel in the S' frame. What is the length and orientation of the rod as measured by a stationary observer in the S frame if the relative speed of the frames is อ' 0.5c as shown in the diagram.
