Question

the Bob of pendulum is realesed from a horizontal position. if the length of the pendulum is 1.5 m, what is the speed with which the bob arives at the lowermost point, given that it dissipacted 5% of course it's initial energy against air resistance ? (take g=10m/s)

Answer 1

l =1.5m
m= mass
dissipated =5%
answer =5.28m /s

Answer 2

8iiiiiiiiiiiiiiiiiiii
