Answer number 4 ACTIVITY 3: PROBLEM SETDirections: Solve the following problems. Show your complete solutions including the freebody diagrams (FBD). Express your final answers in two decimal places.1. A ladder 7.50 m long is leaning against a smooth (frictionless) wall at a point 7.0 mabove the ground. The ladder weighs 200 N and an 800-N painter stands two thirds ofthe way up the ladder. What frictional force must act on the bottom of the ladder toprevent it from slipping for the painter to be safe?2. You hang an object by means of a vertical string. Two strings in turn support this string.String 1 and string 2 make 20° and 60° with the horizontal beam, respectively. Find thetensions in the strings if the mass of the object is 75.0 kg.3. A 15-kg uniform beam is 3.0 m long and is pivoted 1.0 m from the left end. A 35 kgchild sits on the left end of the beam 0.60 m from the pivot. How far from the pivot musta 20 kg child sit in order for the beam to be in equilibrium?4. The diagram below shows a horizontal beam of negligible mass. The wall exerts a 42.0N horizontal force on the lever. Find the mass of the load.string28.01.30 mload1,80 m
