In the first law, an object will not change its motion unless a force acts on it. So I think the answer is A. Only objects that are moving.
<span>this is a dynamometer</span>
10 Km.
S= Speed
D= distance
T= time
S= d/t
but since you are solving for "d" the equation is d=st so you plug in 10 km/h for speed and 2.1 hours for time and just multiply them. The hours cancel out so you are left with 10km.
-- If the object is moving with speed of 10.954 meters per second, then
it has 300J of kinetic energy no matter where it may be located.
-- If the object is 6.118 meters above somewhere, then it has 300J of
gravitational potential energy relative to that place.
Explanation:
w = f x d
45 x 1.4 = 630j
to get newton's do 45 x gravitation field strength
