An object is pulled from rest by a constant, horizontal force of magnitude 6.25 N on a horizontal frictionless surface. In 12 seconds, the object gains a speed of \( 3.0 \mathrm{~m} / \mathrm{s} \). What is the mass of the object, in kg ?

Solve the equation and check the solution. \( -7=\frac{7}{6} r+7 \) \( r=\square \) (Type an integer or a fraction.) \[ \]

Suppose that the functions \( f \) and \( g \) are defined as follows, \[ f(x)=x^{2}+4 \] \( g(x)=\frac{2}{5 x}, x \neq 0 \) Find the composition of a function with itself Simplify your answers as much as possible, \( g \) g, (Assume that your expressions are defined for all \( x \) in the domain of the composition. You do not have to indicate (
