Question

A particle is oscillating in a straight line about a centre o with aforce directed towards o. When at a distance x from o

Answer 1

Explanation:

A particle is oscillating in a straight line about a centre O , with a force directed towards O . When at a distance 'x' from O , the force is mn2x where 'm' is the mass and 'n' is a constant . The amplitude is a = 15 cm . When ata distance a sin 60o from O the particle receives a blow in the direction of motion which generates an extra velocity na . If the velocity is away from O , find the new amplitude . What is the answer , if the velocity of the particle was towards origin .
