Question

Find the total mechanical energy of a mass-spring system with m = 1.22kg and maximum speed 0.700m/s .

Answer 1

F=ma
i don't know if there is enough info in the question

Answer 2

\[K.E=\frac{ 1}{ 2 }mv^2\]

Answer 3

Total mechanical energy = Spring potential energy + kinetic energy
At the point of max. speed, Spring potential energy=0
As such,
Total mechanical energy =\[ \frac{1 }{2 } (1.22 kg)(0.7ms ^{-1})^2\]
