An Unstretched spring with a spring constant of 19.6 N/m is attached to a 2.6 kg block at rest on a horizontal table. A constant 23.6 N force is applied to stretch the spring 41 cm from its resting position. After being let go, what is the speed of the block as it passes equilibrium? A. 3.4 m/s B. 3.1 m/s C. 2.5 m/s D. 7.8 m/s
A spring of force constant 3 N/m is compressed by 5.0 em from its equilibrium position. The spring is then released and stretched by 5.0 ㎝ from its equilibrium position. Find the difference in potential energy between the two positions of the spring (stretched and compressed).

(b) (3 points) A ball of mass m is attached to a spring (with unstretched length lo and spring constant k) which hangs vertically. The ball is initially held at rest with the spring at its unstretched length. Then, the ball is let go. Consider the instant when the ball reaches its lowest position (the spring stretches to its maximum length and s instantaneously at rest), I was done by the spring force during this process (that is from release...
3) Consider Hooke's Law: The force required to keep a spring in a compressed or stretched position x units from the spring's equilibrium position is F(x)-kr Calculate the work required, in joules, to stretch a spring 0.4 meters beyond its equilibrium position for each of the following scenarios. a) The spring requires 50 Newtons of force to hold it 0.1 m from its equilibrium position. b) The spring requires 2 Joules of work to stretch the spring 0.1 meter from...

A spring with spring constant 110 N/m and unstretched length 0.4 m has one end anchored to a wall and a force F is applied to the other end. If the force F does 205 J of work in stretching out the spring, what is the magnitude of F at maximum elongation? Express your answer in newtons.
Suppose a force of 40 N is required to stretch and hold a spring 0.1 m from its equilibrium position. a. Assuming the spring obeys Hooke's law, find the spring constant k. b. How much work is required to compress the spring 0.2 m from its equilibrium position? c. How much work is required to stretch the spring 0.5 m from its equilibrium position? d.

A mass m = 10 kg rests on a frictionless table and accelerated from rest by a spring with spring constant k = 4490 N/m. The floor is frictionless except for a rough patch. For this rough patch, the coefficient of the kinetic friction is µk = 0.5. The mass leaves the spring with speed v = 2.8 m/s. Use work and energy to answer the following questions: (a) How much work is done by the spring as it accelerates...
Consider a spring that does not obey Hooke's law very faithfully. One end of the spring is fixed. To keep the spring stretched or compressed an amount x, a force along the x-axis with x-component Fx=kx−bx2+cx3 must be applied to the free end. Here k=100N/m, b=700N/m2, and c=12000N/m3. Note that x>0 when the spring is stretched and x<0 when it is compressed. A)How much work must be done to stretch this spring by 0.050 m from its unstretched length? B)How...
