Hooke’s Law Worksheet F = kx
1) What force is necessary to stretch a spring whose force constant is 120 N/m by an amount of 30 m?
2) A spring with a force constant of 600 N/m is used in a scale for weighing fish. What is the mass of a fish that stretches the spring 7.5 cm from its normal length?
3) A spring in a pogo stick is compressed 12 cm when a 40 kg boy stands on the stick. What is the force constant for the pogo stick spring?
4) The pygmy shrew has an average mass of 2 g. If 49 of these shrews are placed on a spring scale with a spring constant of 24 N/m, what is the spring’s displacement?
5) The largest meteorite of lunar origin has a mass of 19 g. If the meteorite is placed on a spring scale whose spring constant is 83 N/m, what is the compression of the spring?
6) Male Siberian Tigers average 389 kg. If a male house cat has a mass of 1.5 kg and stretches a spring scale by 1.2 mm, how far would an average sized Male Siberian Tiger stretch the same scale?

A 7 kg mass slides to the right on a surface having a coefficient of friction 0.15 as shown. The mass has a speed of 4 m/s when contact is made with a spring that has a spring constant 101 N/m. The mass comes to rest after the spring has been compressed a distance d. The mass is then forced toward the left by the spring and continues to move in that direction beyond the unstretched position. Finally the mass comes to rest a distance D to the left of the unstretched spring.…
