Amass of 2 kg stretches a spring 4 cm. there is no external force and the mass moves in a medium that impacts a viscous force of 2 n when the speed of the mass is 2 cm/s. if the mass is set in motion from position 1 cm below equilibrium with an initial velocity of 3 cm/s formulate the initial value problem for the motion of the mass x(t). determine the frequency, period, amplitude, and phase of the motion.

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.

In which of the following would the particles move most rapidly? a. ice at -20 °c b. water at 20 °c c. steam at 110 °c d. boiling water e. ice at 0 °c

The electric potential v is constant everywhere within a certain region of space. which statement below is true? the choices are: the electric field is also constant (but not zero) within the region. a charged particle placed within the region will experience an electric force. the electric field is zero everywhere within the region. the electric field varies from place to place within the region.
