Potential energy relative to the surface is
(mass) x (<span>acceleration due to gravity) x (height above the surface).
At 1.0 meter above the surface, that is
</span> (mass) x (<span>acceleration due to gravity) x (1.0 meter) .
The object's mass doesn't change, so the only thing that has any effect
on its potential energy at 1 meter above the surface is the acceleration
of gravity or, in other words, the surface of <em><u>what</u></em> ?

Answer:
shark puppet yeah i be getting buckets
Explanation:
A) The kinetic energy of an object is given by:
where m is the mass of the object, and v its speed. For the lion in our problem, m=45 kg and v=14.2 m/s, so its kinetic energy is
b) the increase in gravitational potential energy of the lion is given by:
where g is the gravitational acceleration, and
is the increase in altitude of the lion. In this problem,
, so the increase in gravitational potential energy is
c) When the fox reaches the top of the tree, its gravitational potential energy is
As it jumps, its kinetic energy is
So the total mechanical energy of the fox as it jumps is
The period, speed and acceleration of a satellite are only dependent upon the radius of orbit and the mass of the central body that the satellite is orbiting. I hope this helps. Sorry if i am wrong.
Answer:
(a) 1294.66 m
(b) 88.44°
Explanation:
d1 = 580 m North
d2 = 530 m North east
d3 = 480 m North west
(a) Write the displacements in vector forms
The resultant displacement is given by
magnitude of the displacement
d = 1294.66 m
(b) Let θ be the angle from + X axis direction in counter clockwise
θ = 88.44°
