An impulse of 40 Ns is transmitted to the rim of a spinning wheel. If the wheel is a flat uniform disc of mass 24 Kg and radius 0,60m, calculate (a) the angular impulse transmitted to the wheel, and (b) the change in angular speed.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

what is the actual question though?
