a) f = k x
b) energy = 1/2 k x^2
c) the total energy equals the kinetic energy of the block
... 1/2 k x^2 = 1/2 m v^2
d) kinetic energy of the block = total energy - energy to stretch 10 cm
e) kinetic energy of the block = total energy - energy to stretch 20 cm
Need help with this problem because I am clueless when it comes to physics. I'd appreciate it if I could get the steps to solving this.
A 10kg block is attached to a spring. The spring has a spring constant of 50N/m and is stretched to a displacement of 50cm. Find the...
a) force of the spring at maximum displacement (amplitude)
b) total energy
c) speed of the block at equilibrium
d) speed of the block at x=10cm
e) speed of the block at x=-20cm
