A fierce spring storm roared up and down Vancouver Island, knocking power out to about 90 thousand customers at the height of the storm.

Spring Force Question…?
A block lies on a horizontal frictionless surface and is attached to the free end of the spring, with a spring constant of 50 N/m. Initially, the spring is at its relaxed length and the block is stationary at position x = 0. Then an applied force with a constant magnitude of 2.8 N pulls the block in the positive direction of the x axis, stretching the spring until the block stops.
Assume that the stopping point is reached.
What is the blocks position when its kinetic energy is maximum?
Value of Kinetic energy = ?mJ

Devastating Wind
MILL BAY – Strong winds destroy docks and smash boats at Mill Bay Marina. Several boats were thrown ashore while others sunk as waves pounded the tiny community. Coastal areas up and down Vancouver Island were hit hard by the Spring storm that also knocked out power to thousands of people. The strong southeast winds led to a number of delays and cancelations for BC Ferries.
What careers are there in Art?
My seventh grade daughter is going to begin a job-shadowing program this spring, but she doesn’t yet know what she wants to “be when she grows up.” She has a natural talent for drawing, and she’s wonderful with little kids, so she thought perhaps an art teacher. But she wants to keep her options open, as well. She wants a career that’s going to make her salary worth the time, money, and energy that she’ll be putting into college, and she’s heard that teachers don’t really make that much money.
Can anyone give me some ideas of art careers and what they consist of? Any web sites would be helpful, too, that she could go to for a free assessment on her talents and passions. Thanks!

i challenge anyone to answer this physics problem!!!?
A spring of negligible mass stretches 3.00 cm from its relaxed length when a force of 6.10 N is applied. A 1.100-kg particle rests on a frictionless horizontal surface and is attached to the free end of the spring. The particle is pulled horizontally so that it stretches the spring 5.00 cm and is then released from rest at t = 0.
(a) What is the force constant of the spring?
N/m
(b) What are the period, frequency, and angular frequency () of the motion?
s (period)
Hz (frequency)
rad/s ()
(c) What is the total energy of the system?
J
(d) What is the amplitude of the motion?
m
(e) What are the maximum velocity and the maximum acceleration of the particle.
m/s (maximum velocity)
m/s2 (maximum acceleration)
(f) Determine the displacement, x, of the particle from the equilibrium position at t = 0.500 s.
m

Particle C and particle D are held together with a compressed ..?
Particle C and particle D are held together with a compressed spring between them. When they are released, the spring pushes them apart and they then fly off in opposite directions, free of the spring. The mass of C is 2.0 times the mass of D, and the energy stored in the spring was 60J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Once that transfer is complete, what are the kinetic energies of (a) particle C and (b) particle D?
explain your answer pleas.

Spring problem for physics!?
A spring of negligible mass has force constant k = 1600 N/m.
How far must the spring be compressed for an amount 3.10 J of potential energy to be stored in it?
You place the spring vertically with one end on the floor. You then drop a book of mass 1.10 kg onto it from a height of 0.900 m above the top of the spring. Find the maximum distance the spring will be compressed.
Take the free fall acceleration to be g = 9.80 m/s^2.
