Answer:
Explanation:
We know that weight of an object on Earth is,
Thus,
where,
m = mass of an object, which is constant and is independent of gravity
g = acceleration due to gravity on Earth
On the new planet, gravity = a
Thus the weight of the object on the new planet will be
Mechanical digestion..............
20.9m = 1s
286.33m = 13.7s
To answer this you would multiply both sides by the amount of seconds she ran. The answer however is that she ran as far as 286.33m.
KE=1/2mv^2
So the 3kg ball rolling at velocity of 3m/s has a KE=1/2(3)(3^2)=27/2=13.5J
The 2kg ball only has a KE=1/2(2)(3^2)=9J
So we can see the 3kg ball has more KE than the 2kg ball because they are moving at the same velocity so the bigger mass has more KE
Air resistance is a force that slows down objects moving through the air. ... Objects are affected by gravity the same, but air resistance can affect the speed of an object's descent. An object with more surface area will have more air resistance.
