An observer in frame S′ is moving to the right (+ x-direction) at speed

u = 0.650 c away from a stationary observer in frame S. The observer in S′ measures the speed v′ of a particle moving to the right away from her.
a)What speed v does the observer in S measure for the particle if v′= 0.430 c ?
b)What speed v does the observer in S measure for the particle if v′= 0.870 c ?
c)What speed v does the observer in S measure for the particle if v′= 0.990 c ?

Two observers agree to test time dilation. They use identical clocks, and one observer in frame S’ moves with speed v=0.8c relative (along +x-axis) to the other observer in frame S. When their origins coincide they start their clocks. They agree to send a signal when each of their clocks reads 90min and to send a confirmation signal when each receives the other’s signal. (a) At what time does the observer in S receive the first signal from the observer...
