tudy a Assignment FULL SCREEN PRINTER VERSION BACK Chapter 10, Problem 45 Go partice (the "bob) at the end of the cable is 0.26 kg. The pendulum is pulled away from its (a) what of a pendulum is 0.75 m and the mass of the resulting oscillatory motion is simple motion. by an angle of released from rest. Assume that friction can be neglected and that the mechanical energy of the is the of the motion? (b) using the position of the bob at its lowest point as the level, determine the total pendulum as it swings back and forth. (c) What is the bob's speed as it passes through the lowest point of the swing? MacBook Pro

Explanation / Answer

a)

angular frequency

w = sqrt ( g/L)

w = 3.614 rad/s

b)

Total energy

E = mgh

E = 0.02249 J

c)

conserving energy

0.02249 = 0.5 mV^2

V = 0.4159 m/s
