A supersonic jet flying at 145 m/s is accelerated uniformly at the rate of 23.1 m/s squared for 20.0 s.

a. What is its final velocity?

b. The speed of sound in air is 331 m/s. How many times the speed of sound is the plane's final speed?

I don't care what it is. Instead of caring about these stupid questions I think you should be caring more about helping childeren with there homework
