A 348 g mass is hung on a spring with a spring constant of 25 N/m.
(a) Find the stretch of the spring when the mass is in equilibrium.
(b) If the mass is lifted 3 cm from equilibrium and then released, find the period of the oscillation.
(c) If the mass instead is hung on a string, pulled to an angle of 16o from the vertical and released, how long should the string be made to obtain twice the period obtained in part (b)?
Only two forces act on a 3.0-kg mass. One of the forces is 9.0 N east, and the other is 8.0 N in the direction of 62° north of west. What is the magnitude of the acceleration of the mass
