the total energy used to move the truck is
(the amount of energy from burning gasoline)
(the amount of energy taken out of the battery) .
(we don't know how much either of those is.)
1.) the objects have the same temperature
this is the answer because thermal equilibrium is when two substances touch and the temperature becomes the same.

answer : the momentum of a man riding his bicycle downhill is 400 kg m/s.
mass of the man of bicycle = 40 kg
velocity of the bicycle = 10 m/s
momentum = mass × velocity = 40 kg × 10 m/s = 400 kg m/s
the momentum of a man riding his bicycle downhill is 400 kg m/s.
rebounds at 13.1 m/s. the ball is in contact
