Question

1. find fgrav using the provided diagram. fnorm = 28 n ffrict = 52 n fapp = 52 n

Explanation:

Step1: Analyze the vertical forces

In the vertical direction, the normal force \(F_{norm}\) and the gravitational force \(F_{grav}\) act on the object. When the object is in equilibrium in the vertical direction (assuming no vertical acceleration), the sum of vertical forces is zero. So, \(F_{norm}-F_{grav} = 0\) (since \(F_{norm}\) is upward and \(F_{grav}\) is downward).

Step2: Solve for \(F_{grav}\)

From \(F_{norm}-F_{grav}=0\), we can rearrange the equation to get \(F_{grav}=F_{norm}\). Given that \(F_{norm} = 28\space N\).

Answer:

\(28\space N\)
