Answer:
An air hockey table has a very smooth and slippery surface which reduces friction by suspending the puck on cushion of air, so that this its motion is much less altered by friction, causing it to glide in a straight line at relatively constant velocity across the table.
Explanation:
Answer:44.58 J
Explanation:
mass of block 
Force magnitude=3 N
Initial velocity =
Final velocity=
Initial Kinetic Energy=
=
Final Kinetic Energy=
=
Work Done =Final -Initial Kinetic energy=51.2-6.612=44.58 J
Answer:
5.59 m/s2
Explanation:
F = 1900 N
m = 340 kg
F = ma
Therefore, a = 1900/340 = 5.59
Fossil fuels like coal for instance , when they are provided with heat energy (heating them) they start producing Kinetic energy . This kinetic energy will be passed along a turbine which transforms this K.E to an electrical energy used in different useful forms.
