The block of mass M in figure -4.160, initially has a velocity v_(o) to the right and its positionis much that the spring exerts no froce on it, i.e, the spring is not stretched or comkpressed. The block moves to the right a distance l before sttoping in the dotted position shown. The speing constant is k and the coefficeent of kinetic friction between block and table is mu. as the block moves the distance l, what is the work done on it by the friction force ? (b) What is the work done on it by the spring force ? (c) are there other forces actionon the block, and if so what work do they do ? (d) what is the total work done on the block?

For an internal combustion engine to move a vehicle down the road ,it must convert the energy stored in the fuel into mechanical energy to drive the wheels. In your car, the distributor and battery provide this starting energy by creating an electrical "spark", which helps in combustion of fuels like gasoline. Below is the reaction depicting complete combustion of gasoline in full supply of air: 2C_8 H_(18)(l) +25 O_(2) (g) to 16 'x' On the basis of evolution/absorption of energy, which of the following processes are similar to combustion of fuel? (a) Photosynthesis in plants (b)Respiration in the human body (c ) Decomposition of vegetable matter (d) Decomposition of ferrous sulphate .
