List of top Physics Questions on work, energy and power asked in AP EAPCET

The velocity-time graph of a body of mass 4 kg moving along a straight line is shown in figure. Work done by all the forces acting on the body from \( t=0 \) to \( t=5s \) is

As shown in figure, a particle slides on a frictionless track which terminates in a straight line horizontal section B. If the particle starts slipping from A, then the horizontal distance to be covered by the particle before it hits the ground after crossing B is:

A body of mass $5\text{ kg}$ is projected vertically upwards from a point $X$ from the ground with an initial speed of $20\text{ ms}^{-1}$. It rises to a point $Y$ where its kinetic energy is reduced to $400\text{ J}$. If the body experiences a constant air resistance of $10\text{ N}$ throughout its motion, then the vertical distance between $X$ and $Y$ is (Acceleration due to gravity $=10\text{ ms}^{-2}$)

An engine pumps water continuously through a hose pipe. If the water leaves the pipe with velocity $v$ and $m$ is the mass per unit length of the water in the pipe, then the rate at which kinetic energy is imparted to the water is:

A system consists of two springs connected in series and each having the spring constant \(10\,\text{N m}^{-1}\). The minimum work required to stretch this system by \(1\,\text{cm}\) in erg is
