1a)A simple pendulum is 4.35 m long. What is the period of simple harmonic motion for this pendulum if it is hanging in an elevator that is accelerating upward at 5.90 m/s2?(adsbygoogle = window.adsbygoogle || []).push({});

b)What is the period of simple harmonic motion for this pendulum if it is placed in a truck that is accelerating horizontally at 5.90 m/s2?

2) A large block P executes horizontal simple harmonic motion as it slides across a frictionless surface with a frequency of f = 1.52 Hz. Block B rests on it, as shown in the figure below, and the coefficient of static friction between the two is μs = 0.630.

What maximum amplitude of oscillation can the system have if block B is not to slip?

1)l=4.35 m

a= 5.90 m/s/s

w^2=g/l

w^2=9.80/4.35

w^2= 2.252873563

then i have to find T.. but i don't know what formula to use...

2) w=2(pie)f

w-2(pie)(1.52 Hz)

w= 9.5504

and i don't know what else to do
