I need help for these two questions (#3 and #4), thank you!! Please show all work and explanations.
pecial theory of relativity, a particle whose mass at rest is M moving with of 3. According to the velocity u will have massthe (constant) speed of ight. Suppose where c is the (constant) speed of light. Suppose at a particular moment a particle is travelling with velocityv a 10 in terms of c. c. How fast is the mass of the particle changing at that moment? Express your answer and has acceleration Suppose that a point is moving in the plane so that at time t (in seconds) the point is located atthe point in the first quadrant where the curves xy = t and y-x + t intersect, where r and y are measured in centimetres. How fast is the distance from the point to the origin changing when t = 1? Note: Your final answer should be in exact form (i.e., no decimal approximations), but you do not need to simplify. d v olt want: d w
