The de Broglie wavelength of a tennis ball of mass 60 g moving with a velocity of 10 metres per second is approximately
What is kinetic energy ? Derive an expressions for the kinetic energy of a body of mass 'm' moving at a speed 'v'.
A ball of mass 50 g falls from rest vertically downwards through a distance of 40 m and hits the ground. Find the kinetic energy and final velocity of the ball before it hits the ground (g=9.8 ms^(-2)) .
