a person is moving in same direction as muon measures lifetime of muon to be 1 micro second if speed of muon and person with respect to lab are c/2 and c/3 .calculate proper life time of muon and distance moved by muon with respect to lab.

A space shuttle of total mass 15000kg is orbiting the earth at a height 5.0x 10^5m above the earth's surface. Assuming that the radius of the earth is 6.4 x 10^ 6m and the gravitational pull of the earth at the surface of the earth is approximately 10m/s^2 . Calculate
I . Gravitational pull of the earth on the space shuttle at that height
ii. weight of the space shuttle at that height
iii. loss of weight of the space shuttle because of its height above the ground

a car is moving on ground with speed 3c/5 and a ball thrown from the car with velocity c/2 in upward directiom what is the velocity of ball with respect to ground.

a source is moving toward observer with velocity c/2 and observer is also moving in same direction with velocity c/3 if the actual frequency of light emmited by source is v0 what is the apperant frequency of light measured by observer

A moving train travels through station P with a speed of 20 meter per seconds anf accelerate uniformly for 2 seconds reaching a speed of 48 meter per second, it continue with this speed for 5 seconds and then retardate uniformly for another 3 seconds and comes to rest at station Q. Find the distance from P to Q
