The period of motion of an object-spring system is T = 0.546 s when an object of mass m = 254 g is attached to the spring.
(a) Find the frequency of motion in hertz.
Hz
(b) Find the force constant of the spring.
N/m
(c) If the total energy of the oscillating motion is 0.228 J, find the amplitude of the oscillations.
m
A 1.5 {rm kg} block rests on top of a 7.5 {rm kg} block. The cord and pulley have negligible mass, and there is no significant friction anywhere. What force F should be applied to bottom block so the top block accelerates to the right at 2.60 m/s^..

Two identical positive charges exert a repulsive force of 7.4 x10-9 N when separated by a distance of 4.8 10-10 m. compute the charge of each.
A 59.0 kg pole vaulter running at 9.5 m/s vaults over the bar. If the vaulter's horizontal component of velocity over the bar is 1.5 m/s and air resistance is disregarded, how high was the jump.
assume the current in the coaxial cable, see the figure , is not uniformly distributed, but instead the current density varies linearly with distance from the center: for the inner conductor and for the outer conductor. Each conductor still carrie..
