consider 3 inertial frame of reference p , q, r , the frame q moves with velocity c/2 with respect to p and r moves with velocity c/10 with respect to q in the same direction. the velocity of r is measured in p will be

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.

Two resistors, 35.5 and 82.3Ω, are connected in parallel. The current through the 82.3-Ω resistor is 4.13A. (a) Determine the current in the other resistor. (b) What is the total power supplied to the two resistors?

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

8. A 1.50 x 103 kg car starts from rest and accelerates uniformly to 18.0 m/s in 12.0 s. Assume that air resistance remains constant at 4.00 x 102 N during this time. Find a) the average power developed by the engine and b) the instantaneous power output of the engine at t=12.0 s, just before the car stops accelerating.

An electron is accelerated from rest to a speed 0.8c by applying potential difference. Find it's value.

A bullet of mass m is fired at speed v0 into a wooden block of mass M. The bullet instantaneously comes to rest in the block. The block with the embedded bullet slides along a horizontal surface with a coefficient of kinetic friction m.
