Question:

A 1.50-kg mass on a spring has displacement as a function of time given by the equation x(t) = (7.40 cm)cos[(4.16 S-I)t - 2.42]. Find
(a) The time for one complete vibration;
(b) The force constant of the spring;
(c) The maximum speed of the mass;
(d) The maximum force on the mass;
(e) The position, speed, and acce1era1ion of the mass at t = 1.00 s; (0 the force on the mass at that time.
