1271 A meterstick is 3 cm wide. At what velocity must the meterstick travel relative to an observer for the observer to find that its length measures the same as its width ? (The stick is moving in a direction parallel to its length.)
A rod has rest frame length ?0=4.3m, and is moving with speed v=0.31c relative to a stationary observer. What length of the rod ? does the observer measure? Answer in meters.
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?
A spacecraft is measured by an observer on the ground to have a length of 53 m as it flies overhead with a speed 17 times 10^8 m/s. The spacecraft then lands and its length is again measured by the observer on the ground, this time while the spacecraft is at rest relative to him. what result does he now get for the length of the spacecraft ? 44 m 53 m 59 m 62 m 64 m The work...
An observer on Earth sees an alien vessel approach at a speed of 0.60c. The Enterprise comes to the rescue (the figure), overtaking the aliens while moving directly toward Earth at a speed of 0.90c relative to Earth (Figure 1) - Part A What is the speed of the Enterprise relative to the alien vessel? Express your answer using two significant figures. VO AQ R o 2 ? lol = Submit Request Answer Part B What is the speed of...
A 200 m long rocketship moves parallel to its length with speed v = 0.9c relative to you. (a) Compute the length of the rocketship measured by you. (b) How long does it take for the rocketship to pass you? (c) In the frame-of-reference of the rocketship, how long does it take for you to travel from one end of the rocketship to the other as you pass by the rocketship? (d) One of the two time intervals calculated in...
Practice Problem 27.3 SOLUTION A spaceship flies past earth with a speed of 0.980c (about 2.97 x 10 m/s) relative to earth. A crew member on the spaceship measures its length, obtaining the value 400 m. What is the length measured by observers on earth? SET UP The length of the spaceship in the frame in which it is at rest (400 m) is a proper length in this frame, corresponding to lo in We want to find the length...
