An electron is moving with a speed of 7.75 β 107 m/s as measured by an observer in a laboratory. the electron is at rest in the primed frame of reference and at its origin. if we assume the origins of the reference frames of the electron and the laboratory are coincident at t = t' = 0 and the electron is moving along the +x axis, what is the position of the electron in the primed frame of reference when the position in the unprimed frame is the following? (assume the electron is at the origin in its reference frame at t = 0.)a. 5.0 mmx'= mmb. 5.0cmx'=. 5.0mx'=. 5.0kmx'=

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
