0.005 kg of copper was heated from 20°c to 80°c. how much energy was used to heat
cu? (specific heat capacity of cu is 385 j/kg °c)
m = 0.005kg
f =80°c
= 20°c
2= ?
= 385 5/kg°c

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.

spare some change and give it to the poor
