List of top Physics Questions on Work Power and Energy asked in TS EAMCET

A block of mass 3 kg is moving down with constant velocity along a rough inclined plane. The work to be done by an external force in pulling the block along the inclined plane through a height of 50 cm is (Acceleration due to gravity $=10\,ms^{-2}$)

The power \(P\) (in watt) acting on a body of mass \(2\text{ kg}\) is given by \[ 4.5P=8t^2+14t+9 \] where \(t\) is time in second. If the body starts from rest at \(t=0\), then the velocity of the body at time \(t=3\text{ s}\) is

A body of mass 0.2 kg is falling freely from a height of 180 m from the ground. The ratio of the works done by the gravitational force in the first two seconds and in the next two seconds of motion of the body is

A body of mass 50 g is projected vertically upwards from the ground. If the kinetic energy of the body at a height of 32 m is 100% more than its potential energy, then the height at which the potential energy of the body becomes 60% of its kinetic energy is

A bullet of mass $m$ moving with a velocity $u$ gets embedded in a block of mass $M$ initially at rest. If $\mu$ is the coefficient of friction between the block and the ground, then the displacement of the block due to the impact is:
