A train started from rest and moved with constant accelera­tion. At one time it was traveling at 33.0 m/s, and 160 m far­ther on it was traveling at 54.0 m/s. Calculate
(a) the acceler­ation,
(b) the time required to travel the 160 m,
(c) the time required to attain the speed of 33.0 m/s,
(d) the distance moved from rest to the time the train had a speed of 33.0 m/s.
