the problem is
a sprinter accelerates from rest to a top speed with an acceleration whose magnitude is 3.8 m/s². after achieving top speed . he runs the remainder of the race without speeding up or slowing down. the total race is 50 meters long. if the total race is run in 7.88s how far does he run during acceleration phase.
the problem is all the equations that i have found are composed of two unknowns so i couldn't solve the problem please help me
