A block of mass M is pulled with a rope on a frictionless surface If a force P is applied at the free end of the rope what will be the force exerted by the rope on the block if the mass of rope is m?
A block of mass M is pulled with a rope on a frictionless surface If a force P is applied at the free end of the rope what will be the force exerted by the rope on the block if the mass of rope is m? Equation#1: Force = mass * acceleration The force P pulls a total mass of (M + m) accelerating both masses at the same rate. Equation #2: P = (M + m) * a Equation #3: a = P ÷ (M + m) At the point where the rope is attached to the block, the block of mass M feels a force making it accelerate at a rate of a = P ÷ (M + m). The force required to make at block of mass M accelerate at a rate of a = P ÷ (M + m) can be determined by equation #4. Equation #4: F of block = mass of block * [P ÷ (M + m)].
A block accelerates at 3.2 down a plane inclined at an angle 30 degrees. Acceleration of gravity is 9.8. Whats the coefficient of static friction between the block and the inclined plane?
Static friction does not apply when the block is already moving. Without friction, the force on the block parallel to the surface of the incline is Fg*sin(angle), so the acceleration without friction is 9.8* sin(30) = 9.8 * (1/2) = 4.9 Since it is accelerating at 3.2, friction is slowing down the block by (4.9-3.2 = 1.7). The coefficient of kinetic friction is (1.7/4.9) = 0.346939

Examples of force of friction that causes an object to accelerate?
Once a particular reference frame is established, whenever friction is observed between two objects, one of the objects speeds up as a result of the frictional force and one of the objects slows down with respect to that reference frame. Imagine a wooden block at rest on an ideal, frictionless surface. If you were to place something on top of the block and drag it across the surface of the block, the friction that resulted would cause the block to move. Since it started at rest and it ended in motion, it sped up as a result of a frictional force. In this example, since the non-frictional forces (the weight of the something you dragged along the top surface of the block) can only be exerted in the direction of the normal, the only force that is left that could possibly cause any movement of the block is due to friction.
The coefficients of friction between a block of mass 1 kg and a surface are s0.64 and k0.42 Assume the only other force acting on the block is that due to gravity what is the magnitude of the fr?
In order for the frictional force to come into play the block must be moving or on the verge of moving. The Frictional force opposes the motion of the block or its "impending" motion. If the block is just sitting on a table with no horizontal forces trying to get it moving then the frictional force is zero.
What is the acceleration of a 38 kg block of cement when pulled sideways with a net force of 245 N?
If, somehow miraculously, the block is on a frictionless slide, and there isno frictional force opposing its horizontal motion, thenF = M AA = F/M = 583/44 = 13.25 m/s2 = about 1.35 G's
A block has acceleration A when pulled by a string If two identical blocks are glued together and pulled with twice the original force what will their acceleration be?
I think so. I'm not a physics expert but see if this makes sense to you.Force = mass * accelerationdouble the mass and you getForce = 2 * mass * accelerationdouble the force with double the mass and you get2 * Force = 2 * mass * accelerationusing simple division math you cancel the 2's which results inForce = mass * accelerationSo I think it would be the same acceleration.
How would the observed value of the acceleration of a block be affected if the one used is heavier?
From f = m*a, a = f/m, so if the force remains constant and the mass increases, the acceleration will decrease. But if the block is on an incline and the force is provided by gravity, the force will increase directly proportional to the mass of the block, and acceleration will remain the same.
What are sticky pistons in Minecraft Xbox 360 Edition used for other then sticking items to it?
That's entirely what they are used for. A normal piston will push a block up, or across, but not pull it back when it retracts. If you need the block to get pulled back, use a Sticky Piston instead.
What would win in a race a truck with a 454 big block or a 350 small block?
The 454 it would have better acceleration
Why does friction never speed up?
Friction always opposes relative motion. It does not oppose motion. Friction is an electric force. It starts acting when two surfaces rub each other. Say a block is pushed and then released, it gets an initial acceleration and its speed starts increasing. Here friction starts playing its part. Friction starts acting on the block in the direction opposite to that of its motion and it also acts on the ground but its effects there are negligible. The friction slowly reduces the acceleration to zero, then at that stage the block has some velocity. Now also friction continues acting backward on it till it comes to rest.Now there is no relative motion or rubbing so no charges appear on the surfaces to provide a frictional force for speeding up the block.
