Question

A spring with a spring constant of 6.2 N m−1 is used to launch a 5.0 g slider along a frictionless track as shown in the figure above. The spring is compressed by 16 cm.

To what height h above the height labeled 0 m in the figure does the slider reach? (in m to 2 s.f)

Answer 1

Answer

Using energy conservation

So height

$H=\frac{0.5kx^2}{mg}\\=\frac{0.5*6.2*0.16*0.16}{0.005*9.81}\\=0.16m$
