Question
The motion of a particle along a straight line is described by equation:x = 8 + 12t - t3 where x is in metre and t in second. The retardation of the particle when itsvelocity becomes zero, is
Options
A.12 ms-2
B.24 ms-2
C.zero
D.6 ms-2
Solution
= 12 - 3t2 = 0 ⇒ t = 2 sec.
= - 6t = - 12 ms-2Create a free account to view solution
