Answer:
In collision between equal-mass objects, each object experiences the same acceleration, because of equal force exerted on both objects.
Explanation:
In a collision two objects, there is a force exerted on both objects that causes an acceleration of both objects. These forces that act on both objects are equal in magnitude and opposite in direction.
Thus, in collision between equal-mass objects, each object experiences the same acceleration, because of equal force exerted on both objects.
Answer: 154.08 m/s
Explanation:
Average acceleration
is the variation of velocity
over a specified period of time
:

Where:

being
the initial velocity and
the final velocity

Then:

Since
:

Finding
:


Finally:

It travels 75 Sin 45 Km Km East and the same distance 75 Cos 45 Km North.
Answer:
dependent: the outcome of the experience
independent variable: everything literaly.
Independent is where you change some variables and see the result
Dependent is literaly the result, or the outcome dependent on the exprience.
Explanation:
I got u.
Vertically (y-axis), horizontally(x-axis)
dy/dt = -0.125 m/s (-ve since y decreasing )
dx/dt = +0.3 m/s (+ve, x increases)
and, x = 5 m
length of the ladder = k (a constant)
k^2 = x^2 + y^2
differentiating it wrt t,
0 = 2x dx/dt + 2y dy/dt
0 = 2(5)(0.3) + 2(y)(-0.125)
y = 12
which means, when the bottom of the ladder is 5m from the wall, the top of the ladder is 12m from the bottom.
thus, k^2 = 5^2 + 12^2
length of the ladder, k = 13 m
