Simply note the sum of their masses, and consider them as one object with that mass.
If you're talking about the acceleration of gravity, and asking how fast two objects tied together will fall,
then none of that matters. Acceleration of a falling object due to gravity is always the same number,
called the "acceleration of gravity". It doesn't matter whether the object is heavy, light, big, small, or
42 separate objects tied together. Under the influence of gravity, trucks, bricks, books, and feathers
all fall with the same acceleration (if air doesn't get in the way).
The force of 5N gives mass m1 an acceleration of 10 m/s^2. From F=ma, we can find the mass m1 as 5N/10m/s^2=0.5kg. Using this mass and the acceleration formula for mass m2 (F=20m*10m/s^2), we find mass m2 as 1kg. When the masses are tied together, the total mass is 1.5kg (m1 + m2), so the acceleration will be 5N / 1.5kg = 3.33 m/s^2.
No, both bricks will fall at the same rate regardless of whether they are tied together or not. This is because the force of gravity acting on an object is only dependent on its mass, not how it is structured.
No. The cyclist is moving at a constant speed, but her velocity is changing. Remember that velocity is speed with a direction vector associated with it. As speed is constant, only direction is changing. But a change in direction is a change in velocity (even if speed is constant), and this requires acceleration in that direction to accomplish the change in direction. You're on the right track, but just recall that acceleration is tied to velocity and not just speed. And note that velocity can change all the time without speed changing. Acceleration must cause the change in velocity. Consider that objects in orbit around the earth move at a pretty constant speed, but accelerate toward the earth all the time. Their speed coupled with their acceleration toward earth cause them to move in an arc - which is their orbital path.
From the laws of nature what ever goes up must come down. This is due to a constant gravitational acceleration which acts on all objects that are on our planet earth. Every object on this planet, independent of size, experiences the same (Constant acceleration) gravitational acceleration so all falling objects have the same acceleration.But a nagging doubt may remain if you are concluding that the gravitational attraction between earth and an object is greater the greater the mass of the object. Here is a non-mathematical way to resolve the dilemma. The more massive object will indeed have a stronger gravitational attraction with earth, but it will also have a greater inertia. (When you think about inertia, the tendency of an object at rest to remain at rest, you might find yourself wondering why the lighter object doesn't hit the ground first!) The combination of gravitational attraction and inertia will be the constant acceleration mentioned above. It still may be difficult to overcome the idea that a heavier object should fall more quickly. Try this mental experiment. Imagine yourself at your antipode, that is, the point on earth that is exactly opposite to your present position. go straight down through the center and come out on the surface. (If that will be water, create a temporary island for a minute.) Now imagine yourself dropping the two objects in a vacuum, and imagine them falling "up" toward the ground. Somehow, imagining it this way makes it easier to see that the greater gravitational attraction is working on a "weightier" or more massive object. It is easier to see that they will naturally "fall" to earth at the same rate of acceleration. Of course, air resistance will cause some differences depending on the materials involved. Drop a bowling ball and a feather from any height, and barring any trickery, the ball will hit the ground first. The acceleration rate for objects falling toward earth (that would have to be corrected for air resistance) is 9.8 meters/seconds squared. In a vacuum, there is no correction necessary for air resistance.
The best way to answer that question is: Because that's the way gravity works. When you think about it, it's really the only way that makes sense. Let's assume that heavy things fall faster, and light things fall slower. Take a heavy thing and a light thing. Tie them together with 3 feet of string, and drop them from a high building. The light thing wants to fall slower, and it holds the heavy thing back. The heavy thing wants to fall faster, and it pulls the light thing ahead. Together, they fall at some speed faster than the light thing alone, but slower than the heavy thing alone. Bu that's crazy. What difference does it make whether they're tied together with string, stuffed in the same bag together, or hooked together with nuts and bolts ? Together, they're even heavier than the heavier thing, but we just said that they're falling slower than the heavier thing would fall alone. It doesn't add up. Heavier things don't fall faster.
The force of 5N gives mass m1 an acceleration of 10 m/s^2. From F=ma, we can find the mass m1 as 5N/10m/s^2=0.5kg. Using this mass and the acceleration formula for mass m2 (F=20m*10m/s^2), we find mass m2 as 1kg. When the masses are tied together, the total mass is 1.5kg (m1 + m2), so the acceleration will be 5N / 1.5kg = 3.33 m/s^2.

Convert the speed to meters per second. Use the formula acceleration = speed squared / radius to find the centripetal acceleration. Then use the formula force = mass x acceleration to find the corresponding force.

The duration of three tied semiquavers is equivalent to a dotted quaver.
The sight of 3 bamboo stalks tied together is believed to be lucky in many countries. The stalks are even braided together at times.
They do, in-fact get more hang time when they are tied together.
