How fast should a meter stick be moving in order to appear to be only 60cm?
How fast should a meter stick be moving in order to appear to be only 60cm?
How fast must a meter stick be moving if its length is observed to shrink to 0.65 m?
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?
How fast would it have to be going past you in order for it to appear only 5.55 m long? Give you answer as a ratio of the velocity to the speed of light c. Consider a 6.05 m long sports car going past you at great speed.
How fast does a proton have to be moving in order to have the same de Broglie wavelength as an electron that is moving at 5.20 × 106 m/s?
Consider hanging masses off the ends of a meter stick which is nailed to the wall, as shown the figure. Take the meter stick to be a 1.0 m long massless rod, the nail is d = 12 from the end as shown, and it is free to rotate about this point. If I put a mass m_1 = 5.0 kg onto the left of the meter stick, how much mass m_2 should I put onto the right end to...
A 1 kg mass is hanging off the 0 cm mark of a massless meter stick that is resting on a fulcrum at the 20 cm mark. How much mass must be placed at the 100 cm mark in order to make the meter stick balance? 1/4 kg 1/2 kg 1/5 kg 2/3 kg 1/3 kg
A new meter stick has dimensions of 100 cm by 2.5 cm by 0.60 cm and has a total mass of 70.0 grams. Assume the density of the stick is uniform throughout. a.) What is the linear mass density of the meter stick? b.) If somebody drills 0.50 cm diameter holes at the 60, 70, 80 and 90 cm marks, where will the new center of mass for the meter stick be located? c.) If a 50 gram mass is...
