Two charged spheres on a frictionless horizontal surface are attached to opposite ends of a 750 N/m spring & are in static equilibrium. The 24 kg red sphere has more charge than the 9 kg green sphere. The total charge magnitude on the spheres is 59 μC & they have opposite polarity. As a result the spring is compressed 0.03 m & the centers of the spheres are 0.57 m apart. Determine the charge magnitude on each sphere.

A block with mass 0.400 kg is on a horizontal frictionless surface and is attached to a horizontal compressed spring that has force constant k=200 N/m. The other end of the spring is attached to a wall. The block is released, and it moves back and forth on the end of the spring. During this motion the block has speed 3.00 m/s when the spring is stretched 0.160 m. (a) During the motion of the block, what is its maximum...

A positive charge q1 = 2.90 μc on a frictionless horizontal surface is attached to a spring of force constant k as in the figure shown below. when a charge of q2 =-9.100 μC is placed 9.50 cm away from the positive charge, the spring stretches by 5.00 mm, reducing the distance between charges to d = 9.00 cm. Find the value of k. The response you submitted has the wrong sign. N/m 1 42

A 4.86 kg block free to move on a horizontal, frictionless surface is attached to one end of a light horizontal spring. The other end of the spring is fixed. The spring is compressed 0.104 m from equilibrium and is then released. The speed of the block is 1.01 m/s when it passes the equilibrium position of the spring. The same experiment is now repeated with the frictionless surface replaced by a surface for which $\mu$k = 0.275. Determine the...

A mass of 9 kg is placed on a horizontal frictionless surface and attached to a spring. The mass is compressed 0.69 meters on the spring from equilibrium and held still. It is then released and it travels across the horizontal surface, around a frictionless quarter circular ramp, and it is launched into the air vertically and reaches a maximum height of 6 meters above the ground. The same mass is then attached to the same spring and hung vertically...
