A 22 g mass is pushed with a force of 13 N, a=? A 6 N force is accelerating at 44 m/s2, what is the mass?

A mass is accelerated at 78 m/s2. If the mass is 31 g, what force had to be put on it?

A 1200 g man runs up a hill with an acceleration of 5 m/s2. What is his force?

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
