A thin hollow cylinder, open at both ends and weighing 5kg (a) slides with a speed of 10 m//s without rotating (b) rolls with the same speed without slipping. Compare the kinetic energies of the cylinder in the two cases.

Calculate the kinetic energy of a 20 kg wooden cart moving with a speed of 5 m/s. Calculate the kinetic energy again when the speed is doubled.

A student, weighing 45 kg, is running with a speed of 8 km per hr on a foot path 2m wide. A small car, weighing 1200 kg, is moving with a speed of 60 km per hr on a 20 m wide road. Calculate their de Broglie wavelengths.
