Q. A 3.00 kg mass is associated to a spring with a spring constant of 6.0 N/m. The velocity is given by the expression v(t) = 10cm/s sin(wt). What is the maximum velocity of simple harmonic motion? vx(t) = -vm sin(wt)
Q. Suppose a 61 kg boy and a 43 kg girl use a mass less rope in a tug-of-war on an icy, resistance-free surface. If the acceleration of the girl toward the boy is 3.0 m/s2, find the magnitude of the acceleration of the boy toward the girl.
