Inertia is the property of movement (properly velocity).
Inertia is most commonly referenced in connection to Newton's laws of motion, in that an object in motion stays in motion. This (normally, anyway) isn't true in everyday life, as forces like friction, gravity, et cetera, fight back causing velocity to be converted to heat. Objects to which this doesn't apply, like space probes, keep moving forever.
Answer:
v_kyle = 0.5 m/s
v_jennies = 0.333 m/s
Kyle's Rabbit was the fastest
Explanation:
For the velocity of Kyle's Rabbit:
d = distance covered = 40 m
t = time taken = (1 min)(60s/1 min) + 20 s = 80 s
<u>v_kyle = 0.5 m/s</u>
For the velocity of Jennies Rabbit:
d = distance covered = 30 m
t = time taken = (1 min)(60s/1 min) + 30 s = 90 s
<u>v_jennies = 0.333 m/s</u>
It is clear from the results that:
<u>Kyle's Rabbit was the fastest</u>
The sun gets its power from nuclear fusion. In the suns core.
Answer: 217.52 N
Explanation: The applied force is 20 N, the distance covered is 12.0 m and the angle is 25° above the horizontal.
Hence the formulae that defines work done is given by
W = Force × distance
But since the force has been inclined at an angle θ above the horizontal, the horizontal component of force is neccesary to produce the required motion to make the child do work on the wagon.
Hence
Work done = (horizontal component of force) × distance
Work done = F cos θ × distance
Work done = 20 cos 25 × 12 = 217.52 N
