If a is the amplitude of a mass on an oscillating spring, then in one period the mass travels a distance of

a. 0
b. a
c. 2a
d. 4a

d. 4A

Explanation:

Given that

Amplitude = A

We know that the distance cover by a particle before coming the the rest from the mean point in the oscillation motion is known as amplitude.

The distance cover by particle from 1 - 2 = A

The distance cover by particle from 2 - 1 = A

The distance cover by particle from 1 - 3 = A

The distance cover by particle from 3-4 = A

Therefore the total distance cover by particle = A+A+A+A = 4 A

Therefore the total distance = 4 A

That is why the answer will be 4 A.

d. 4A

probably not if net force is zero
