A rocket ship is propelled vertically up with an acceleration of g in a uniform gravitational field.A pendulum of length 1.0 m would have a period of
A)0
B)2.0 s
C)1.41 s
D)3.1 s
E)the period is infinite

Quizplus · Accepted Answer

The effective acceleration acting on the pendulum is 2g (g from gravity and g from the rocket's acceleration). The period T of a pendulum is given by T = 2π√(L/g_eff), where L is the length and g_eff is the effective acceleration. Substituting L = 1.0 m and g_eff = 2g, we get T = 2π√(1/2g) = 2.0 s.
