We know that a force of 7.2 Newtons is required to stretch a certain spring 0.8 meters beyond its natural length. Questions Q1 (0/10) A 2.56-kg mass is attached to this spring and allowed to come to equilibrium. The mass-spring system is then set in motion by applying a push in the upward direction that gives the mass an initial velocity of 1.15 meters per second. Q2 (0/10) Q3 (0/10) Q4 (0/10) Q5 (0/10) Q6 (0/10) Let y(t) represent the...

The work required to stretch a spring 1.2 meters beyond its natural length is 36 Joules. The force required to hold the spring at a length of 6 meters is 100 Newtons. Find the natural length of the spring.
A spring has a natural length of 10 cm. If a 29-N force is required to keep it stretched to a length of 26 cm, how much work w is required to stretch it from 10 cm to 18 cm? (Round your answer to two decimal places.) W 3 Need Help?
A spring has a natural length of 20 cm. If a 26-N force is required to keep it stretched to a length of 38 cm, how much work W is required to stretch it from 20cm to 29 cm? (Round your answer to two decimal places.) W = ______ J
Hooke’s Law states that the force required to maintain a spring stretched x units beyond its natural length is proportional to x, i.e. f(x) = kx where k is a positive constant. Suppose that 4 J of work is needed to stretch a spring from its natural length 10 cm to a length of 36 cm. Find the exact value of work needed to stretch the spring from 15 cm to 28 cm.
A force of 10 lb is required to hold a spring stretched 4 in. beyond its natural length. How much work W is done in stretching it from its natural length to 10 in. beyond its natural length?
A spring has a natural length of 22 cm. If a 28-N force is required to keep it stretched to a length of 40 cm, how much work w is required to stretch it from 22 cm to 31 cm2 (Round your answer to two decimal places.) W =
