**Problem 4: Kinematics and Energy**A 15 kg box slides down a bumpy track as shown in the diagram, starting from rest at a point 12.7 meters above the ground.**a) If there is no friction, how fast is the box moving at the bottom?****b) If friction does -200 J of work on the box as it slides, how fast is the box moving at the bottom?****Diagram Explanation:**The diagram shows a vertical drop of 12.7 meters. At the top of this height, a box is poised to slide down a track that has a bumpy appearance. The box ends at the bottom moving horizontally with a final velocity denoted as \( v \). Key Points:- The initial position is 12.7 meters above the ground.- The track is bumpy, which may imply varied slopes and curves, but these are not specified quantitatively in this context.- The questions explore the effects of friction and its absence during motion down the track.

1. A 23.0 kg child is playing on a swing with a length of 2.5 m. If the swing starts from rest and makes an angle of 40.0◦ with the vertical at the top of the swing, a) determine the child’s speed at the bottom of the swing neglecting friction. b) If the swing has a speed of 2.8 m/s at the bottom, determine the work done by friction during the downswing and, bonus) assuming the force of friction is constant, determine the maximum angle the swing attains on the upswing after passing through the bottom. Hint: Use the approximation that cos θ ≈ 1 − 1 2 θ 2 for angles given in radians.
