A). balanced force
b). unbalanced force
There's no such thing as either of these. A group of two or more forces can be balanced or unbalanced. A single force can't be.
c). gravitational force ... doesn't cause an object to move in a circle;
Drop a stone from the roof of a tall building and watch it fall.
It goes straight down, not in a circle.
d). centripetal force ... force directed toward the center of a circle,
causes an object to move in a circle.
Answer:
<u>Velocity impact is 50.86 m/s.</u>
Explanation:
If an "object of mass" "m" is dropped from "height" "h", then the "velocity" just before impact is "v" . The "kinetic energy" before impact is equal to its "gravitational potential energy" at the height from which it was dropped: Kinetic energy = J.
V is impact velocity
h height in meter = 132 m
V = 50.86 m/s
<u>Velocity impact is 50.86 m/s</u>.
Answer:
Part a)
Part b)
Magnitude of the force is given as
Part c)
As we know that Y component of the force is negative so here the force is directed below the X axis
Explanation:
Part a)
Adrienne apply the force of 20 N along +X direction and Jim apply force of 40 N at 53 degree above negative X axis
so we will have
now let say the force exerted by Luis is F such that sum of all forces must be zero
now we have
so we have
Part b)
Magnitude of the force is given as
Part c)
As we know that Y component of the force is negative so here the force is directed below the X axis
So here we have
Answer:
I think the sun is the answer
