List of top Physics Questions on Work-energy theorem asked in KEAM

A bullet of mass 0.05 kg entering a heavy wooden block with a speed of 100 ms\(^{-1}\) is stopped in a distance of 50 cm. The average resistive force exerted by the block on the bullet is

A body of mass \( 0.2\,\text{kg} \) travels along a straight line with velocity \( v = (2x^2 + 2)\,\text{m s}^{-1} \). The net work done by the driving force during its displacement from \( x = 0 \) to \( x = 2 \,\text{m} \) is

Work- energy theorem in an integral form of

A ship of mass \(2\times10^7\) kg initially at rest is pulled by a force of \(5\times10^5\) N through a distance of \(2\) m. Assuming that the resistance due to water is negligible, the speed of the ship is

The Work-Energy theorem

A vehicle moving at 36 km/hr is to be stopped by applying brakes in the next 5 m. If the vehicle weighs 2000 kg, determine the average force that must be applied on it

Some of the following equations are kinematic equations, where the symbols have their usual meaning. The work-energy theorem is represented by

Displacement, $x$ (in meters), of a body of mass $1$ kg as a function of time, $t$, on a horizontal smooth surface is given as $x = 2t^2$. The work done in the first one second by the external force is
