A small block of mass m is kept on rough inclined surface of inclination θ fixed in an elevator. The elevator goes up with a uniform velocity v and the block does not slide on the wedge. The work done by the force of friction on the block in time t will be Work done [...]

A block of mass M is hanging over a smooth and light pulley through a light string. The other end of the string is pulled by a constant force F. If kinetic energy of the block increases by 20J in 1s. Then: Work done from d = 0 m to d = 3 m October [...]

Consider the situation shown in figure. Initially the spring is unstretched when the system is released from rest. Assuming no friction in the pulley, the maximum elongation of the spring is Consider the situation shown in figure. Initially the spring is unstretched when the system is released from rest. Assuming no friction in the pulley [...]

A block of mass m is attached to two unstretched springs of spring constant k₁ each as shown . The block is displaced towards right through a distance of x and released. Find the speed of the block as it passes through the mean position will be Work done from d = 0 m to [...]

A mass of 0.5 kg moving with a speed of 1.5 ms^−1 on a horizontal smooth surface, collides with a massless spring of force constant k = 50Nm^−1.The maximum compression of the spring would be A mass of 0.5 kg moving with a speed of 1.5 ms^−1 on a horizontal smooth surface collides with a [...]

A simple pendulum of length 1m has bob of mass 100 g. It is displaced through an angle of 60^∘ from the vertical and then released. The kinetic energy of bob when it passes through the mean position is Work done from d = 0 m to d = 3 m October 21, 2020 Category: [...]

The figure shown a particle sliding on a frictionless track, which terminates in a straight horizontal section. If the particle starts slipping from the point A, how far away from the track will the particle hit the ground? how far away from the track will the particle hit the ground? The figure shown a particle [...]
