A block of mass 100g slides on a rough horizontal surface. If the speed of the block decreases from 10 m s–1 to 5 m s–1, find the thermal energy developed in the process.
Given:
mass of block=0.1kg
Formula used:
kinetic energy=1/2mv2
M=mass
V=velocity
Change in kinetic energy = thermal energy developed
3.75J=thermal energy developed
