Question

29. The velocity of a train increases at a constant rate a from 0 to v and then remains constant for some
time interval and then finally decreases to zero at a constant rate ß. If the total distance covered by
the particle be x, then show that the total time taken will be
t=x/v + v/2(1/a + 1/beta)​

Answer 1
