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
Because when your running any experiment there will always be an experimental error so always be ready for it so that you can correct that error in your experiment
The difference between living things and nonliving things is little things that we call is senses like sight, taste, touch, smell, and hearing. For example a human or animal can react to someone or something touching them. For a nonliving thing such as a rock can't react to someone touching them unless u force them to.
I can confirm, your answer is 800J (Or 800 Joules)!
I just took the test and this was the correct answer :)
Answer:
the time at which it passes through the equilibrum position is:
t = 0.1 second
Explanation:
given
w= 4pounds
k(spring constant) = 2lb/ft
g(gravitational constant) = 10m/s² = 32ft/s²
β(initial point above equilibrum) = 1
velocity = 14ft/s
attached is an image showing the calculations, because some of the parameters aren't convenient to type.
