Answer:
a) 0.78 s
b) 58.86m/s'
c) Galileo's law of free fall
Explanation:
a) 
b)At the bottom:
kinetic energy = potential energy
downwards
c) Galileo's law of free fall says regardless of the masses, bodies in a vacuum will fall, on the earth, at the same acceleration
Mass = 1.2 kg = 1200 grams.
Volume = mass/density = 1200 cm3.
Hope this helps!
This is a true and false question correct or did you accidentally put two truths ??
<span>A. a momentum of 540 grams per meters per second
The momentum equation is p = mv. P is the variable for momentum, m is the variable for mass and v is the variable for velocity. To find the momentum, you must multiple the mass of the object by the velocity it is traveling by. The unit for momentum is the mass per meter per second.</span>
