An object of mass 9.00 kg attached to an ideal massless spring is pulled with a steady horizontal force across a frictionless level surface. If the spring constant is 95.0 N/m and the spring is stretched by 10.0 cm , what is the magnitude of the acceleration of the object?

Respuesta :

Answer:

Acceleration of the object will be [tex]1.05m/sec^2[/tex]

Explanation:

We have given mass of the object m = 9 kg

spring constant k = 95 N/m

Spring is stretched by 10 cm

So x = 10 cm = 0.1 m

We know that force is given by [tex]F=kx=95\times 0.1=9.5N[/tex]

From newton's law we also know that force is given by

F = ma , here m is mass and a is acceleration

So [tex]9.5=9\times a[/tex]

[tex]a=1.05m/sec^2[/tex]
