Answer:
4 N to the right
Explanation:
For the object in this problem, we have 2 forces acting on it:
- A force of 2 N, to the right
- A force of 2 N, to the right
The two forces are in line: this means that the two vectors can be simply added by calculating their algebraic sum.
If we take right as positive direction, the two forces can be written as
F1 = +2 N
F2 = +2 N
So, the net force will be

And the positive sign means the direction is to the right.
Answer:
Yes.
Explanation:
A kilometer is less than a mile, therefore if a horse can finish one mile in less than 2 minutes then it can certainly do a kilometer in less than two minutes.
The formula for speed is s = d/t, where s is speed, d is distance, and t is time. The formula can be applied to all objects, including cars, to find their speed.
Explanation:
Terminal velocity is given by:

Here, m is the mass of the falling object, g is the gravitational acceleration,
is the drag coefficient,
is the fluid density through which the object is falling, and A is the projected area of the object. in this case the projected area is given by:

Recall that drag coefficient for a horizontal skydiver is equal to 1 and air density is
.

Without drag contribution the motion of the person is an uniformly accelerated motion, thus:

Answer:
True
Explanation:
If it weren't from a 90 degree angle then the circle would be a bit more oval shaped
