Question

A block is attached to a horizontal spring and set in simple harmonic motion, as shown in the figure. At what point in the motion is the acceleration of the block at its maximum? The position of the block when the spring is relaxed is marked by x = 0, and th extremes of the block's motion are at x = A and x = -A. EXPLAIN. Plz :)

Question 3 of 8 presanted by Mapoob UNIVERSITY PHYSICS Philip R. KestenDavid L.Tauck sapling leaming A block is attached to a horizontal spring and set in simple harmonic motion, as shown in the figure. At what point in the motion is the acceleration of the block at its maximum? The position of the block when the spring is relaxed is marked by x 0, and the extremes of the block's motion are at x A and x =-A. x = A and x =-A x=0and x = A x=0 x= A

Explanation / Answer

Here ,

for the maximum acceleration ,

the force acting on the object must be maximum

spring force is given as

force = k * x

hence , force is maximum when magnitude of x is maximum

which is equal to amlitude

hence , the accleration of the block is maximum at x = A and x = - A
