A train started from rest and moved with constant acceleration. At one time it was traveling 30 m/s, and 160 m farther on it was traveling 50 m/s. Calculate
(a) The acceleration,
(b) The time required to travel the L60 m mentioned,
(c) The time required to attain the speed of 30 m/s, and
(d) The distance moved from rest to the time the train had a speed of 30 m/s.
(e) Graph x versus t and y versus / for the train, from rest.
