Create some variable names for the different unknown velocities. See what equations you can write to relate them.Vv anand said:
Yes that i hv already done... Will start again.. Thxharuspex said:
Is it 3##\delta##Chestermiller said:
No. Look at the diagram carefully.Vv anand said:
Oh is it 4 ##/delta##Chestermiller said:
Just because of the middle string attached to the mass coming from the upper left pulleyVv anand said:
No. Look carefully. The wire between pulleyVv anand said:
Sir I am coming to the solution that since pulley supporting B moves up the pulley supporting a moves down 3##/delta## as i hv to keChestermiller said:
Yes sir...i got that the ##/pulley## is moving delta downwardsVv anand said:
Wrote that upper comment by mistake...Vv anand said:
Sir vbChestermiller said:
But this brings me to the solution that vb=2/3.Vv anand said:
Yes. So?Vv anand said:
I guess I don't agree.Vv anand said:
I confirm 0.5m/s.Chestermiller said:
Yes, that works.Vv anand said:
Newton's laws of motion apply to a block in a pulley system because they describe the relationship between the forces acting on an object and its resulting motion. In this case, the block experiences both gravitational force and tension force from the pulley system, which can be calculated using Newton's laws.
The formula for finding the velocity of a block in a pulley system is v = (a * t) + v0, where v is the final velocity, a is the acceleration, t is the time, and v0 is the initial velocity. This formula is based on the second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it.
The number of pulleys in a system does not affect the velocity of the block, as long as the pulleys are frictionless. This is because according to the third law of motion, for every action, there is an equal and opposite reaction. Therefore, the tension force acting on the block is the same regardless of the number of pulleys, resulting in the same acceleration and velocity.
Yes, Newton's laws of motion can be used to calculate the velocity of a block in a pulley system in real-life situations. However, it is important to consider factors such as friction and the weight of the pulleys, which may affect the accuracy of the calculations. In some cases, other variables may also need to be taken into account, such as the mass and shape of the block.
The velocity of a block in a pulley system can be measured experimentally by using a motion sensor to track the position of the block over time. This data can then be used to calculate the velocity using the formula v = (xf - x0) / t, where xf is the final position, x0 is the initial position, and t is the time. Alternatively, the velocity can also be measured using a ticker-tape timer, where the time between each mark on the tape can be used to calculate the velocity.
