Ke=1/2mv^2
Ke= 0.5*30*20^2
Ke= 6000joules
Answer:
Explanation:
The system of equation is the following:
We can solve the system by expliciting C from the second equation. We get:
And if we know substitute C into the first equation, we find
And by substituting D into the second equation, we find
Since the net force is the amount of force favoring the side with the most force acted upon it,
100 - 50 = 50
50N to the left

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
