Power P = work/time = mgd/t = mgv
=) v = P/mg = 120 /3.5×9.8 = 120/ 34.3 = 3.49m/s
Hence required velocity v = 3.5m/s
Please give a thumb up. Thank you.

A bucket and a counter-weight are used to lift water out of a well. The bucket and counter-weight are attached to either end of a light rope that passes over a light, frictionless pulley, with the rope hanging straight down to both. The mass of the counter-weight is greater than the mass of the bucket filled with water. The bucket starts at the bottom of the well and the counter-weight starts at the top. The counter-weight is released from rest...
A bucket weighing 2 kg and a
rope of negligible mass is used todraw water from a well that is
40.8 meters deep. Just before thebucket starts being raised from
the bottom of the well, the bucket isfilled with 6 kg of water.
Unfortunately, there is a hole in the bucketand water leaks out at
the rate of 0.12 kg per second. The bucketis pulled up at a
constant rate of 0.8 meters per second.(a)How much water is in the...
a. water is to be raised from a well 40 feet deep by means of a bucket attached to a rope. When the bucket is Ib 12. Water is wder it weighs 50 lb, but the bucket has a leak that causes it to lose water at a constant rate of 3 for every 7 feet that the i full of water it wei bucket is raised.. Neglecting the weight of the rope, set up and evaluate fthe he work...
A bucket of water of mass 14.4 kg is suspended by a rope wrapped around a windlass, that is a solid cylinder with diameter 0.350 m with mass 13.0 kg . The cylinder pivots on a frictionless axle through its center. The bucket is released from rest at the top of a well and falls a distance 10.0 m to the water. You can ignore the weight of the rope. Take the free fall acceleration to be g = 9.80...
A bucket that weighs 6 lb and a rope of negligible weight are used to draw water from a well that is 50 ft deep. The bucket is filled with 36 lb of water and is pulled up at a rate of 2.5 ft/s, but water leaks out of a hole in the bucket at a rate of 0.25 lb/s. Find the work done in pulling the bucket to the top of the well. Show how to approximate the required...
A bucket of water of mass 15.7 kg is suspended by a rope wrapped around a windlass, that is a solid cylinder with diameter 0.280 m with mass 11.4 kg . The cylinder pivots on a frictionless axle through its center. The bucket is released from rest at the top of a well and falls a distance 10.6 m to the water. You can ignore the weight of the rope. Part A What is the tension in the rope while...
A bucket weighing 10N and holding 0.01m of water is suspended by a rope weighing 5N/m in a well 20 m deep. The bucket is leaking at a rate of0.0002m/s. How much work is necessary to raise it to the top at a steady rate of 1 m/s?
A bucket weighing 10N and holding 0.01m of water is suspended by a rope weighing 5N/m in a well 20 m deep. The bucket is leaking at a rate of0.0002m/s. How much...
A bucket (m = 4.0 kg ) is falling down to a 25 meter deep well as shown in the figure. The cylindrical drum has a mass of 28 kg and radius of 15 cm. 33. find the tension in the rope, T = ? 25m 34. find the linear acceleration of the descending bucket. 35. find the angular acceleration of the descending bucket. 36. find the final angular velocity of the cylinder when the bucket touches the bottom of...
A bucket of water of mass 2kg makes it a way
down to the bottom of a water well. The bucket of water is
suspended from a rope which is attached to a hoist with a radius of
0.04m at the top of the water well.
What is the acceleration of the water bucket if the hoist is
submitted to a moment of force of friction of
= 0.15 N*m (Let the hoist be a full
cylinder with a mass...
A 4.61 -kg bucket of water is raised from a well by a rope. If the upward acceleration of the bucket is 3.37 m/s2 , find the force (N) exerted by the rope on the bucket.
