A shopper weighs 2.50 kg of apples on a supermarket scale whose spring obeys Hooke's law and notes that the spring stretches a distance of 2.00 cm.
(a) What will the spring's extension be if 5.50 kg of oranges are weighed instead?cm
(b) What is the total amount of work that the shopper must do to stretch this spring a total distance of 8.50 cm beyond its relaxed position?

You have a light spring which obeys Hooke's law. This spring stretches 2.24 cm vertically when a 3.00 kg object is suspended from it. Determine the following. (a)the force constant of the spring (in N/m) N/m (b)the distance (in cm) the spring stretches if you replace the 3.00 kg object with a 1.50 kg object cm (c)the amount of work (in J) an external agent must do to stretch the spring 7.90 cm from its unstretched position J
When a 3.80-kg object is hung vertically on a certain light spring that obeys Hooke's law, the spring stretches 2.60 cm. (b) How much work must an external agent do to stretch the same spring 4.00 cm from its unstretched position? _____J
When a 3.80-kg object is hung vertically on a certain light spring that obeys Hooke's law, the spring stretches 2.30 cm. (a) If the 3.80-kg object is removed, how far will the spring stretch if a 1.50-kg block is hung on it? x When an object is 'hung' from a spring, the spring force is equal in magnitude to the gravitational force. cm (6) How much work must an external agent do to stretch the same spring 4.00 cm from...
