Question

Rylan stands on his bathroom scale in the morning and finds that he weighs 610 N. He takes a ride in an elevator, and much to the amusement of the other passengers, he brings his bathroom scale and stands on it during the ride. Assuming that the acceleration due to gravity is 10 m/s2, determine the reading on the scale while the elevator accelerates upward at 2 m/s2.

An observer or Earth determines the distance to Proxima Centauri, our nearest star, to be 3.97 x 10 13 km. Determine this distance as determined by an astronaut travelling in a spaceship at a speed of 0.98c

Explanation / Answer

1) F= m(g+a)
mg= 610 N
m= 61 kg

F= 61(10+2)
F= 720 N


2) L = L0(1-(v/c)2)1/2

  L = 7.9x1012 km
