(1 point) A bucket of water of mass 30 kg is pulled at constant velocity up to a platform 25 meters above the ground. This takes 20 minutes, during which time 2 kg of water drips out at a steady rate through a hole in the bottom. Find the work needed to raise the bucket to the platform. (Use g = 9.8m/s².) Work = (include units)

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 6-kg bucket of water is being pulled straight up by a string at a constant speed. What is the tension in the rope? A) about 42 N B) about 60 N C) about 78 N
A bucket that has a mass of 10 kg when filled with sand needs to be lifted to the top of a 30 meter tall building. You have a rope that has a mass of 0.4 kg/m that must be secured to the bucket. It takes 1 meter of rope to secure the bucket. Once the bucket reaches the top of the building it only has mass 6 kg because there was a hole in the bottom and sand was...
# 3 Points possible: 1. Total attempts: 6 A bucket that has a mass of 20 kg when filled with sand needs to be lifted to the top of a 15 meter tall building. You have a rope that has a mass of 0.4 kg/m that must be secured to the bucket. It takes I meter of rope to secure the bucket. Once the bucket reaches the top of the building it only has mass 12 kg because there was...
14. A bucket of mass m is being drawn up a well by a rope which exerts a steady force F. Initially the bucket contains a mass mo of water, but this leaks out at a constant rate so that after time t the bucket is empty, before it reaches the top of the well. What is the velocity of the bucket when it is just empty? 14. A bucket of mass m is being drawn up a well by...
A 2.20 kg bucket containing 11.0 kg of water is hanging from a vertical ideal spring of force constant 120 N/m and oscillating up and down with an amplitude of 3.00 cm. Suddenly the bucket springs a leak in the bottom such that water drops out at a steady rate of 2.00 g/s. A)When the bucket is half full, find the rate at which the period is changing with respect to time. B)What is the shortest period this system can...
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...
