A 3.0 kg cube on a spring (k=280 N/m) oscillates in simple harmonic motion. The cube has a speed of 0.55 m/s when it is 0.020 m from the equilibrium position.
(a) find the amplitude of motion.
(b) determine the cubes maximum velocity.
The peak wavelength for the blackbody radiation from a star corresponds to an energy of 2.92x10^ -19 J. what is the temperature of the star at the surface
A 2.00-kg object moves with constant velocity 3.00 m/s toward the east. Two forces act on the object. The first is a 40.0 N force toward the west. What is the second force that acts on the object
