Question

The bob of a simple pendulum of mass m and total energy E will have maximum linear momentum equal to

• A. $\sqrt { \frac { 2 E } { m } }$
• B. $\sqrt { 2 m E }$
• C. 2Me
• D. mE

Answer 1

Answer: (B)

$\sqrt { 2 m E }$

Answer 2

$E = \frac { P ^ { 2 } } { 2 m }$ where E = Kinetic Energy, P = Momentum,

m = Mass

So $P = \sqrt { 2 m E }$.
