A particle that hangs from a spring oscillates with an angular frequency of 2 rad//s . The spring particle system is suspended from the celling of an elevator car and hangs motionless (relative to the elevator car) as the car descends at a constant speed of 1.5 m//s . The car then stops suddenly. (a) With what amplitude does the particle oscillate ? (b) What is the equation of motion for the particle ? (Choose upward as the position diriction)

A mass m is kept hanging by a rad of length L. What tangential velocity must be given to it so that it can just reach the top of the vertical circle ?

If the coefficient of static friction between a table and a uniform massive rope is mu , what fraction of the rope can hang over the edge of a table without the rope sliding.

An article is sold at a certain price. If it is sold at 80% of this price, then there will be a loss of 10%. What is the percentage profit when the article is sold at the original selling price? एक वस्तु किसी निश्चित कीमत पर बेची जाती है | यदि इसे इस कीमत के 80% पर बेचा जाए, तो 10% की हानि होगी | वस्तु को आरंभिक विक्रय मूल्य पर बेचने पर होने वाला प्रतिशत लाभ ज्ञात करें |

A uniform chain of mass m and length l is lying on a horizontal table with one-third of its length hanging over the edge of the table. If a gentale pull is given to hanging end, it will start moving down. What is the change in gravitational potential energy of the chain, as it jist leaves the table?

A uniform chain of mass m_0 and length l rests on a rough incline with its part hanging vertically as shown in the fig. The chain starts sliding up the incline (and hanging part moving down) provided the hanging part equals eta times the chain length ( eta lt 1). What is the work performed by the friction force by the time chain slides completely off the incline. Neglect the dimension of pulley and assume it to be smooth.
