The packages slide along the surface ABC to a conveyor belt which moves with a velocity of 2 ms. Knowing that k 0.25 between the packages and the surface ABC determine the distance d if the packages are to arrive at C with a velocity of 2 ms. SOLUTION The problem deals with a change in position and different velocities so use work-energy

A box is dropped from a very small height and lands on a conveyor belt. The belt is moving horiontally at 5 ms. Consider the following times. Time A A short time after the box lands on the belt it is moving horiontally at 2 ms. Time B Ten seconds after the box lands on the belt it is moving at the same speed as the belt
2006-10-19having trouble setting these style of problems up. please take a look. problem A student it running at a constant velocity of 6.00ms to catch the campus shuttle bus which is stopped at the bus stop. When the student is 80 m from the bus it starts to pull away with a constant acceleration
Relative velocity is defined as the velocity of an object from the reference point of another object. I could leave it at that but thats boring so heres an example. Imagine a ball on a conveyor belt. Its velocity from your reference point is n
A 2.00 kg block moves a distance d 1.50 m horiontally to the left. A constant force 6.00 N directed 40.0o above the horiontal acts on the block as shown in the diagram. How much work is done on the block by the force during the 1.50 m displacement

2012-10-28 0.5 s. 3 A The conveyor belt exerts a force friction of sie . F k m g. This constant force accelerates the packet in the forward direction F m a so a k g until its speed relative to the belt is ero it then just sits on the belt under static friction. The time it takes the speed of the package to reach the speed of the belt is
If the velocity of A is 2 ms downward determine the velocity of B at the instant 45. 70. Solution Vector Analysis Kinematic Diagram. Since points A and B are restricted to move along the fixed slots and vA is directed downward the velocity vB must be directed horiontally to the right. 71
The figure below shows a conveyor belt oriented at an angle that moves uphill and to the left at a constant speed vb. A block of mass m slides down a ramp and then gets deposited on the belt with. The radius of the pulley is 8 cm. If the mass falls at a constant velocity of 2 ms
A 0.075 kg ball in a kinetic sculpture moves at a constant speed along a motoried conveyor belt. The ball rises 1.32 m above the ground. A constant frictional force of 0.350 N acts in the direction opposite the conveyor belts motion. What is the net work . asked by Brian on December 9 2010 Physics
