Question

4
А force of
stretches
the spring 30cm. A body of
maso
4 kg is hung from the
Spring. Then the spring is
Pulled
down 10 cm
and released
a) calculate period of oscillation.
(b) Find the direction and magnitude of acceleration if the mass is 5 cm above from equilibrium.

(c) What is the shortest time required to go to equilibrium position?


​

Answer 1

Explanation:

Period of oscillation is 2pi sqrt(m/k) no matter what so that would be 2pi sqrt(4/k)

equilibrium is the position where the net force is zero so the force should be acting downward

i guess you can calculate the rest of it cuz I am a bit lazy rn
