Answer:
The maximum speed at the lowest height will be 2.4 m/s.
Explanation:
As the pendulum will be exhibiting maximum kinetic energy when it reaches the lowest point say h =0 and lowest potential energy at this point. So according to law of conservation of energy.
K.E = potential energy
So the velocity at the lowest point will be [tex]v = \sqrt{2gh}[/tex]
As g is given as 9.8 m/s2 and h is given as 0.3m , then the maximum speed will be
[tex]v=\sqrt{2*9.8*0.3}=2.4 m/s[/tex]
Thus, the maximum speed at the lowest height will be 2.4 m/s.
