Problem

A train leaves a station with an initial velocity of

2\,\text{m/s}

and travels in a straight line with a uniform acceleration of

1.0\,\text{m/s}^2

. The train covers a displacement of

150\,\text{m}

during this phase of motion. Attempt the following: a. (a) Using suitable symbols, write the relation connecting displacement, initial velocity, acceleration and time for uniformly accelerated motion. b. (b) Form an equation in the unknown time

t

for the data given above and solve it to obtain the possible values of

t

. c. (c) Comment briefly on the physical relevance of each root obtained in part (b).
