Question

Neglecting friction, what's its speed when it leaves the spring? also, repeat previous part if the coefficient of kinetic friction is 0.290. Neglecting friction, what's its speed when it leaves the spring? Neglecting friction, what's its speed when it leaves the spring? also, repeat previous part if the coefficient of kinetic friction is 0.290. Neglecting friction, what's its speed when it leaves the spring? also, repeat previous part if the coefficient of kinetic friction is 0.290. A horizontal spring with g block is pushed onto the free end, compressing the spring by 0.160 N/m has one end attached to the wall. A 290 k = 130

Explanation / Answer

a)

=(1/2).29KG(V^2)-(1/2)130Nm(.16m)^2 Then solve for V^2

= .145kg (V^2) -1.664N

SQRT of (1.664N / 145kg)= V^2

3.388 m/s=V
