Work done from d = 0 m to d = 3 m

A ball is projected vertically upwards with a certain initial speed. Another ball of the same mass is projected at an angle of 60^∘ with the vertical with the same initial speed. At highest points of their journey, the ratio of their potential energies will be Work done from d = 0 m to d [...]

Two equal masses are attached to the two ends of a spring of spring constant k. The masses are pulled out symmetrically to stretch the spring by a length x over its natural length. The work done by the spring on each mass is Work done from d = 0 m to d = 3 [...]

The potential energy of a certain spring when stretched through a distance ‘S’ is 10 joule. The amount of work (in joule) that must be done on this spring to stretch it through an additional distance ‘S’ will be Work done from d = 0 m to d = 3 m October 21, 2020 Category: [...]

If the kinetic energy of body is directly proportional to time t, the magnitude of force acting on the body is (i) directly proportional to t√ (ii) inversely proportional to t√ (iii) directly proportional to the speed of the body. (iv) inversely proportional to the speed of the body. If the kinetic energy of body [...]
