A hucket drops sand vertically onto a moving conveyor-belt at the rate of 5.70 kgis. The rubber conveyor-belt is supported by wheels (frictionless) and moves at a constant speed of tha motor that drivas the belt. - D.710 m/s under the action of a constant horizontal axternal force supplied by Figure P9.87 (a) Find the sands rate of change of momentum in the horizontal direction. (b) Find the force ot friction exerted by the belt on the sand (c) Find...
020 10.0 points Sand from a stationary hopper falls on a mov- ing conveyor belt at the rate of 6.8 kg/s, as shown in the figure. The belt is supported by frictionless rollers and moves at 0.783 m/s un der the action of a horizontal external force supplied by the motor that drives the belt Find the frictional force exerted by the belt on the sand Answer in units of N.
A baggage handler drops your 8.30 kg suitcase onto a conveyor belt running at 2.90 m/s. The materials are such that = 0.450 and mu_k = 0.230. How far is your suitcase dragged before it is riding smoothly on the belt?
A baggage handler drops your 8.30 kg suitcase onto a conveyor belt running at 2.70 m/s . The materials are such that μs = 0.460 and μk = 0.150. How far is your suitcase dragged before it is riding smoothly on the belt?
A baggage handler drops your 7.70 kg suitcase onto a conveyor belt running at 1.70 m/s . The materials are such that μs = 0.410 and μk = 0.150. How far is your suitcase dragged before it is riding smoothly on the belt?

5. (20 points) A horizontal conveyor belt moving at 3 m/s receives sand from a container. The sand falls vertically from the container to the belt at a speed of 1.5 m/s and a flow rate of 200 kg/s. The conveyor belt is initially empty but begins to fill with sand. If the friction in the drive system and rollers is negligible. find the force required to pull the belt while the conveyor is filling. sand...
Problem 5-14 The conveyor belt shown a or the belt is L 20 ft. (a) Determine the angle a for which the sand is deposited on the stockpile at B (b) If the sand falls with practically zero velocity onto the conveyor at a constant rate m 100 lbm's as shown below, determine the magnitude of the net force P required to maintain a constant belt speed v (use the smaller of the two angles v 30 m/s n below...
A boxed 10.0 kg computer monitor is dragged by friction 5.50 m up along the moving surface of a conveyor belt inclined at an angle of 35.9 above the horizontal. If the monitor's speed is a constant 2.10 cm/s, how much work is done on the monitor by friction, gravity, and the normal force of the conveyor belt?
A 1.2 kg ball drops vertically onto afloor, hitting with a speed of 20 m/s.It rebounds with an initial speed of 10 m/s. (a) What impulse acts on the ball during thecontact? kg·m/s (b) If the ball is in contact with the floor for 0.020 s, what is the average force exerted on thefloor? N
