Answer:

Explanation:

Depends on the location of the two forces. If they are aligned on the same side of the object, you would simply add.

X -----------F1 -------F2

X is the object. F1 and F2 are both masses which create a gravitational force. They both are the form of Fx = G * m1 * m2 / r^2. The total force is F1 + F2

If they are are on either side of the object, you subtract.

F1 ---------X ---------F2

Fx = F1 - F2

Any other location of F1 and F2 is much more complicated by the use of trigonometry.

When an airplane is sitting on the ramp, which of Newton's Laws does it exhibit?

antiseptic1488 [7]

It shows the first law of Newton.

The first law states that :-

'If an object is at rest it will be at rest or if it is at motion, it will be in the state of motion until an external force is applied'

Since the airplane is at rest, it will be at rest showing the first law

Pin p is constrained to move along the curve defined by the lemniscate r=(4sin2θ)ft.if the slotted arm oa rotates counterclockwi

ruslelena [56]

position of the peg is given by the equation

$r = 4 sin2\theta$

now the rate of change in position is given as

$v = \frac{dr}{dt}$

$v = \frac{d}{dt}(4 sin2\theta)$

$v = 8cos2\theta*\frac{d\theta}{dt}$

$v = 8 cos2\theta*\omega$

given that

$\omega = 1 rad/s$

$\theta = 59 degree$

now we have

$v = 8*cos(2*59)* 1 = -3.76 m/s$

so its speed will be 3.76 m/s in magnitude

Is it possible for an object moving with a constant speed to accelerate? explain?

Andreas93 [3]

Yes, as long as it hasn't reached its maximum speed. Think of a car going 30mph, it can remain at this speed and travel at a constant rate; however, the car could also increase it's speed further. Hope this answers your question.
