A certain spring has a spring constant k1 = 720 N/m as the spring is stretched from x = 0 to x1 = 39 cm. The spring constant then changes to k2 = 210 N/m as the spring is stretched to x2 = 67 cm. From x2 = 67 cm to x3 = 91 cm the spring force is constant at F3 = 115 N.

The earth remains in orbit around the sun due to the force of gravity. how does the force of gravity exerted by the sun on the earth compare to the force of gravity exerted by the earth on the sun?

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
