A spring gun of spring constant `90N/cm` is compressed `12cm` by a ball of mass `16g` . If the trigger is pulled, the velocity of the ball is

A massless spring of length l and spring constant k is placed vertically on a table. A ball of mass m is just kept on top of the spring. The maximum velocity of the ball is

A spring of spring constasnt 50 N/m is compressed from its natural position through 1 cm. Find the work done by the work done by the spring force on the agency compressing the spring.

A 15 gm ball is shot from a spring whose spring has a force constant of 600 N//m . The spring is compressed by 5 cm . The greatest possible horizontal range of the ball for this compression is

A spring with spring constaant k when compressed by 1 cm the PE stored is U. If it is further compressed by 3 cm, then change in its PE is

A spring with spring constaant k when compressed by 1 cm the PE stored is U. If it is further compressed by 3 cm, then change in its PE is

A block of mass m sliding n a smooth horizontal surface with velocity vecv meets a long horizontal spring fixed ast one end and having spring constant k as shown n figure. Find the maximum compression of the spring. Will the velocity of the block be the same as v whenit comes back to the original position shown?

A string of length 40 cm and weighing 10 g is attached to a spring at one end and to a fixed wall at the other end. The spring has a spring constant of 160 N m^-1 and is stretched by 1.0 cm. If a wave pulse is produced on the string near the wall, how much time will it take to reach the spring ?
