568 muons were counted by a detector on the top of mount washington in a one hour period of time. assuming moving muons keep time at the same rate as stationary muons, then 27 should survive until sea level. the fact that 412 muons were detected by the same equipment at sea level reveals that
a. the stationary clock measures time differently at different altitudes
b. the moving clocks keep time at the same rate as stationary clocks
c. that moving clocks run slower
d. that moving clocks run faster

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
