Because gravity is constant
<span>the only force acting in free-fall is gravity which points downward at 9.8 m/s</span>
No it can't it's material
Answer:
to the right
Explanation:
The balls collide in a completely inelastic collision, in other words they have the same velocity after the collision, this velocity has a magnitude V.
We need to use the conservation of momentum Law, the total momentum is the same before and after the collision.
In the axis X:
(1)
With the given values of , we have
Try dealing with the powers of 10 first: On the right, we have
Meanwhile, the other values on the right reduce to
Then taking units into account, we end up with the equation
Now we solve for :
or, if taking significant digits into account,
