QUESTION NO. 5: MANDATORY/ OPTIONAL /O BONUS (8 POINTS) a) An object of mass 1 kg compressed a spring of force constant 500 N/m a distance of 10 cm. The object then is released to move a distance d=1m on a rough plane of kinetic friction coefficient uk =0.05 and then on a smooth incline plane. Find the speed of the object when it moves to a height of H=10 cm. b) A light bulb of power 100 W works 3 hours a day. Find the consumed electric energy in kWh per month.
