Question

3.
A particle moves along a striaght line. The position
of the particle varies with time as X = 40 +
12t ^- t^3.The distance travelled by particle in
between t = 0 to till it comes to rest is X is in
metre and t in seconds)
(1) 24 m
(2) 40 m
(3) 56 m
(4) 16 m​

Answer 1

Answer:

56meter

Explanation:

diffrentiate the equation so we get the velcity

v= 12-3t2

we see that at t=2 v=0

therefore total time is 2sec

putting t=2 In the equation we will get x=56meters
