Answer:
15.5 Millimeters = 1.55E-5 Kilometers
Explanation:
Answer:
Here we do not have the vector, but I will try to give a kinda general solution to this type of problem.
If the vector is written as (a, b, c) we have that the force in the x-axis is of a Newtons, in the y-axis is of b Newtons, and in the z-axis is of c Newtons.
Then, we can calculate the total magnitude of this force as:
F = √( a^2 + b^2 + c^2)
wich gives us the total magnitude of the force, but not a direction or anything like that, this is just a scalar.
It’s a I hope this helps you out

Answer:
a. is the time after which the two stone hit the water surface.
b.
c. &
Explanation:
Given:
- height of the cliff,
- time gap between the projection of stones,
- initial velocity of first stone,
Here positive sign means that the stone is thrown vertically downward in the direction of gravity.
a.
Using equation of motion:
is the time after which the two stone hit the water surface.
b.
using the equation of motion for second stone:
c.
Final velocity of the stone at the instant of touching the water surface:
&
