A 2 kg mass hangs motionless from a partially stretched spring having a spring constant of 198 N/m. What is the magnitude of the force (in N) that would be required to pull the mass down by an additional 4 cm? Never include units with your answer.
using hooke's law
F = k x
F = 198* 0.04
F = 7.92 N

comment in case any doubt, will reply for sure.. goodluck

A 50 g mass hanger hangs motionless from a partially stretched spring. When a 50 gram mass is added to the hanger, the spring stretch increases by 9 cm. What is the spring constant of the spring (in N/m)? (Assume g = 9.79 m/s2.) Never include units with your answer.
A single mass (m1 = 4.3 kg) hangs from a spring in a motionless elevator. The spring constant is k = 266 N/m. 1) What is the distance the spring is stretched from its unstretched length? 2) Now, three masses (m1 = 4.3 kg, m2 = 12.9 kg and m3 = 8.6) hang from three identical springs in a motionless elevator. The springs all have the same spring constant given above. What is the magnitude of the force the bottom...
A single mass (m1 = 4.4 kg) hangs from a spring in a motionless elevator. The spring constant is k = 270 N/m. 1) What is the distance the spring is stretched from its unstretched length? 2) Now, three masses (m1 = 4.4 kg, m2 = 13.2 kg and m3 = 8.8) hang from three identical springs in a motionless elevator. The springs all have the same spring constant given above. What is the magnitude of the force the bottom spring exerts on the...
A single mass m1 = 3.5 kg hangs from a spring in a motionless elevator. The spring is extended x = 15 cm from its unstretched length. 1) What is the spring constant of the spring? Now, three masses m1 = 3.5 kg, m2 = 10.5 kg and m3 = 7 kg hang from three identical springs in a motionless elevator. The springs all have the same spring constant that you just calculated above. What is the force the top...
A single mass m1 = 4.4 kg hangs from a spring in a motionless elevator. The spring is extended x = 14 cm from its unstretched length. Now, three masses m1 = 4.4 kg, m2 = 13.2 kg and m3 = 8.8 kg hang from three identical springs in a motionless elevator. The springs all have the same spring constant that you just calculated above. 1) What is the force the top spring exerts on the top mass? 2) What...
A spring having a spring constant of 125 N/m hangs from a support and a 4.0 kg mass is attached to the other end. The mass is raised so that the spring is un-stretched and released from rest. How fast (in m/s) is the mass traveling after it has fallen 0.5 m?
A proud deep-sea fisherman hangs a fish of mass 61.0 kg from an ideal spring having negligible mass. The fish stretches the spring a distance of 0.119 m What is the force constant of the spring? What is the period of oscillation of the fish if it is pulled down and released?
A 1.10 kg mass hangs from a spring of force constant 400 N/m . The mass is then pulled down 13.0 cm from the equilibrium position and released. At the end of five complete cycles of vibration, the mass reaches only 10.0 cm from the equilibrium position. Part A: How much mechanical energy is lost during these five cycles? Part B: What percentage of the mechanical energy is lost during the five cycles?
A spring with spring constant 13 N/m hangs from the ceiling. A ball is attached to the spring and allowed to come to rest. It is then pulled down 8.5 cm and released. The ball makes 29 oscillations in 15 s seconds. What is its the mass of the ball? Express your answer to two significant figures and include the appropriate units. What is its maximum speed? Express your answer to two significant figures and include the appropriate units.
A spring with spring constant 10 N/m hangs from the ceiling. A ball is attached to the spring and allowed to come to rest. It is then pulled down 5.5 cm and released. The ball makes 27 oscillations in 23 sseconds. Part A What is its the mass of the ball? Express your answer to two significant figures and include the appropriate units. m = Part B What is its maximum speed? Express your answer to two significant figures and...
