### Kinematics

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,

and

(d) the distance moved from rest to the time the
train had a speed of 33.0 m/s.
