27.11 A meter stick moves past you at great speed.Its motion relative to you is parallel to its long axis. If you measure the length of the moving meter stick to be 1.90ft for example, by comparing it with a ruler that is at rest relative to you, at what speed is the meter stick moving relative to you?
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...
A meter stick hurtles through space at a speed of 0.95c relative to you, with its length perpendicular to the direction of motion. You measure its length to be equal to -0.05m - 0m -1.00m -1,05 m 0.95m
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 uniform 172 g meter stick rotates about an axis perpendicular to the stick passing through its center with an angular speed of 6.25 rad/s. (a) What is the magnitude of the angular momentum of the stick? (b) What would be the angular speed of the meter stick if it is rotated with the same angular momentum as in part (a) but about an axis of rotation situated at one end of the meter stick and parallel to the axis...
A slender uniform rod 100.00 cm long is used as a meter stick. Two parallel axes that are perpendicular to the rod are considered. The first axis passes through the 50-cm mark and the second axis passes through the 11-cm mark. What is the ratio of the moment of inertia through the second axis to the moment of inertia through the first axis? Answer in two decimal places.
A meter stick is traveling past you at 0.6125c with its length pointed in the direction of its velocity. From your perspective, how long is the meter stick? Please show the steps legibly.
You attach a meter stick to an oak tree, such that the top of the meter stick is 2.27 meters above the ground. Later, an acorn falls from somewhere higher up in the tree. If the acorn takes 0.201 seconds to pass the length of the meter stick, how high above the ground was the acorn before it fell (assuming that the acorn didn't run into any branches or leaves on the way down)?
A 2.1 meter long baseball bat travels in a direction that is parallel to its length. An observer at rest on the Earth measures the bat's length to be 1.5 meters. What is the speed of the baseball bat relative to the stationary observer (give your answer in terms of “c”) ?
A uniform meter stick is placed on and parallel to the x axis, with the 50 cm mark at the origin. It is pivoted at the 50 cm mark. A -5.91 N force is applied at the 48 cm mark, and a -2.79 N force is applied at the 61 cm mark. Calculate the net torque on the rod. NOTES: Define up to be the +y-directidh. Remember to define the sign of the torque by the sense of rotation it...
