010 (part 1 of 2) 10.0 points A crate is lifted vertically 1.5 m and then held at rest. The crate has weight 100 N (i.e., it is supported by an upward force of 100 N). How much work was done in lifting the crate from the ground to its final position? 1. No work was done. 2. None of these 3. More than 150 J 4. A bit less than 150 J 5. 150 J 011 (part 2 of...
When a 2.00-kg object is hung vertically on a certain light spring described by Hooke's law, the spring stretches 2.78 cm. (a) What is the force constant of the spring? N/m (b) If the 2.00-kg object is removed, how far will the spring stretch if a 1.00-kg block is hung on it? cm (c) How much work must an external agent do to stretch the same spring 9.00 cm from its unstretched position?
A 10.0 N force does +5.00 J of work on a 2.00 kg object. The displacement of the object during this time is 3.00 m. What is the angle between the force and the displacement vector?
a 4kg object is lifted vertically 2.0m and then returned to its original position. how much work did GRAVITY do on the bucket during the process?
A 2.50 kg object falls vertically downward in a viscous medium at a constant speed of 2.50 m/s. How much work is done by the force the viscous medium exerts on the object as it falls 80.0 cm?
