What is the area of the frame when it moves parellel to one of its diagonal with a m² speed of 0.86.c as indicated in the figure? >V.arrow_forwardAn astronent travels to a distant star with a speed of 0.44C relative to Earth. From the austronaut's point of view, the star is 420 ly from Earth. On the return trip, the astronent travels speed of 0.76c relative to Earth. What is the distance covered on the return trip, as measured by the astronant? your answer in light-years. with a Give ly.arrow_forward

It then hits a stationary block B (1kg) which then slides to a maximum distanced before it stops. Determine the value of d.The coefficient of static friction between theblock and the plane is μk = 0.2. The coefficientof restitution between A and B is e = 0.8.Ans: d=1.0034 marrow_forward
