Answer: Potential energy is energy stored in an object due to its position or arrangement. Kinetic energy is the energy of an object due to its movement its motion. Potential energy can be converted into kinetic energy, and kinetic energy can be converted into potential energy.
Answer:
2 m/s^2
Explanation:
from the question
v=15 m/s
t=7.5
a=?
from the first equation of motion
v=u+at
where,
v=final velocity
u=initial velocity
a=acceleration
t=time
from the question (u) will be zero because the body started at rest
v=u+at
15=(0)+a×7.5
15=7.5a
a=15/7.5
a=2 m/s^2
Answer:
20 N up
Explanation:
Since the object on the floor is sitting still. Based on Newton's law of force. Objects must have equal reaction and force against each other for still objects. So the answer is 20 N up. Since the force are equal on both sides making the object not moving.
B. 8.89 (hope this helped.)
You can solve by just doing 3.5in * 2.54
