Is the motion simple harmonic??Please help me

Can u please give your method

Homework Statement a rope is tied between 2 walls as shown.a bead of mass 'm' is on the rope as shown. it is constrained to move in the horizontal direction. it is tied to a spring of force constant 'k'- N/m. the spring is initially at its free length 'H'. the bead is displaced by a small...

A)find the condition such that a "projectile fired at an angle theta from an inclined plane of angle of inclination "alpha" on to another inclined plane of angle of inclination "beta" retraces its path after the first collision"? NOTE : the collision is elastic, alpha not equal to beta...

a rectangular rigid fixed block has a long horizontal edge. a solid homogenous cylinder of radius r is placed horizontally at rest wid its length parallel to the edge such that the axis of the cylinder and the edge of the block are in the same vertical plane. there is sufficient friction present...

prove that the acceleration of a body moving with constant speed in ellipse is always directed towards one of the focus . I have tried but my efforts have gone in vain

well on working out the problem i got the answers 1) , but there is a multiple answer to the question

A particle having mass m and charge q moves along a line under the action of an electric field E = alpha – beta *x where alpha and beta are positive constants and x is the distance from a point where the particle was initially at rest. Then, for an observer moving with acceleration q*alpha/m...

it is ok. thank you for u r insights

hey that is mit open course

i wiil study your solution

In part (a), there is perfect balance at all points, so each mass will have acceleration = 0. Proof: At the last pulley, there are equal masses on each side, so it will not turn. Now on the next pulley above it, the mass on the left equals the sum of the masses on the right, so it will not...

A peculiar Atwood’s machine The Atwood’s machine shown in the figure consists of masses m,m/2,m/4,...,m/(2^(N-1)). All the pulleys and springs are mass less, as usual a) Put a mass m/(2^(N-1)) at the free end of the bottom spring. What are the acceleration s of all the masses b) Remove...

thankyou very much
