as it is given that it covers a total distance 1 * 10^2 m
total time taken by it = 13.6 s
now the average speed is given as ratio of total distance and total time
so the average speed will be 7.35 m/s
now if it starts from rest and achieve the final speed as 7.35 m/s
now we can use kinematics
so its acceleration will be 3.68 m/s^2
Explanation:
Given that,
The vertical motion of mass A is defined by the relation as :
At t = 1 s
x = 115.33 mm
(a) We know that,
Velocity,
At t = 1 s
v = 18.94 mm/s
We know that,
Acceleration,
At t = 1 s
(b) For maximum velocity,
t = 45 seconds
For maximum acceleration,
t = 61.8 seconds
Hence, this is the required solution.
