Where the question says "2.8 g", we understand that to mean
2.8 times the acceleration of gravity = 27.44 m/sec2 .
F = M A = (1.2 kg) x (27.44 m/s2) = 32.928 newtons
Heat IS produced by friction.

Friction can produce energy in the form of heat
Yes, it does produce heat energy.
I have no clue!^ Why answer it then when you don't have any information to contribute?Friction can produce heat. I'm not sure if this is the best answer, but it's something.. right? :)
When you are playing bowling you exert energy by swaying your hands as you role the bowling ball to the bowling pin.The physics applied is Kinematics :) ====================== We call it rolling without slipping. Its an extraordinary motion which friction allows us to produce. Normally if we try to roll a circular object without friction it wont roll but it would slip on the surface. But on having friction we have a couple in action which is now able to produce torque. This torque helps the object to move forward.
Different substances produce different amounts of friction. But generally, rough surfaces produce the maximum friction.
When the brakes are applied, the car's kinetic energy is converted to heat by friction between the brake pad and the brake disk.

you can produce it by making the suface rougher and who asked this!?
Yes.
rubbing your hands together produce heat that is friction.
