Answer:
(i) , (ii)
, (iii)
Explanation:
(i) and
represent the points where particle has a velocity of zero and spring reach maximum deformation, Given the absence of non-conservative force and by the Principle of Energy Conservation, the position where particle is at maximum speed is average of both extreme positions:
(ii) Maximum accelerations is reached at and
.
(iii) Greatest net forces exerted on the particle are reached at and
.
Answer:
3.95979 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
Here
Initial velocity of the puck should be 3.95979 m/s
