A train slows down at a constant rate as it

rounds a sharp circular horizontal turn. Its

initial speed is not known. It takes 19.8 s to

slow down from 81 km/h to 37 km/h. The

radius of the curve is 164 m.

As the train goes around the turn, what is

the magnitude of the tangential component of

the acceleration?

Answer in units of m/s2.

At the moment the train’s speed is 55 km/h,

what is the magnitude of the total accelera-

tion?

Answer in units of m/s2.
