Acar travels in reverse. it covers 150 meters in 12 seconds what is the velocity of the car what is the speed of the car

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?

Could we see a galaxy that is 20 billion light-years away?
