im sorry this question is weird the school has some weird ones lol A large rock is much heavier than a small water balloon. Yet,

you observe that they fall at a similar rate. Why is this? The larger size of the large rock slows it down to the small water balloon speed. Water balloons change shape so that they can fall faster. The force pulling the large rock down is greater, but it takes more force to move it. The golf ball may be smaller, but it is denser.

Answer: It will be necessary for you to erect of the water. not readily oxidized, and also having a In the construction of some of our large public buildings, this simple yet efficient method of (25) C. Z.M. says: I am building a small engine with link motion New shoots come up, but they in turn are killed off long before maturity. and no the golf ball is not denser even tho it sinks

Explanation:

Any two objects that have mass attract each other with a force we call gravity.  You probably never noticed this for small objects, because the force is so weak.  But the Earth has lots of mass, and so it exerts a big gravitational force on you.  We call that force your weight.  The fact that gravity is actually a force of attraction is not obvious.  Prior to the work of Isaac Newton, it was assumed that gravity was simply the natural tendency of objects to move downward. this is why they

There’s a time with gravity where no matter what the objects move at the same force. There’s a point where it reaches its max speed and cannot go faster.

An airplane flies eastward and always accelerates at a constant rate. At one position along its path it has a velocity of 34.3 m
Tomtit [17]

Explanation:

We'll need two equations.

v² = v₀² + 2a(x - x₀)

where v is the final velocity, v₀ is the initial velocity, a is the acceleration, x is the final position, and x₀ is the initial position.

x = x₀ + ½ (v + v₀)t

where t is time.

Given:

v = 47.5 m/s

v₀ = 34.3 m/s

x - x₀ = 40100 m

Find: a and t

(47.5)² = (34.3)² + 2a(40100)

a = 0.0135 m/s²

40100 = ½ (47.5 + 34.3)t

t = 980 s

If the angular velocity of the pully is -8.4rad/s at a given time, and its anglar acceleration is -2.8rad/s2, what is the angula
snow_lady [41]

Here we know that

\omega_i = - 8.4 rad/s

\alpha = - 2.8 rad/s^2

t = 1.5 s

now from kinematics we have

\omega_f = \omega_i + \alpha t

now from above all values we have

\omega_f = (-8.4 rad/s) + (-2.8 rad/s^2)(1.5)

\omega_f = -8.4 + (-4.2)

\omega_f = -12.6 rad/s

so final angular speed is -12.6 rad/s

Calculate the force at sea level that a boy of mass 50 kg exerts on a chair in which he is sitting.
kogti [31]

As per the question the mass of the boy is 50 kg.

The boy sits on a chair.

We are asked to calculate the force exerted by the boy on the chair at sea level.

The force exerted by boy on the chair while sitting on it is nothing else except the force of gravity of earth i.e the weight of the body .The direction of that force is vertically downward.

At sea level the acceleration due to gravity g = 9.8 m/s^2

Hence the weight of the boy w = mg  [m is the mass of the body]

we have m = 50 kg.

                             Hence w = 50 kg ×9.8 m/s^2

                                             =490 N kg m/s^2

                                              = 490 N

Here newton [N] is the unit of force.
