Question

figure shows an downhill plane with the dimensions as H = 15 m, D = 19 m, and an angle ? = 54.14o. Incline has a coefficient of kinetic friction of μk = 1.90.
The block of mass m = 2.8 kg starts at labelled point 1 with an initial speed v1 which slides to the labelled point 2.

This image depicts a right-angled triangle, often used to illustrate concepts in geometry or physics related to inclined planes. ### Diagram Description: 1. **Triangle Orientation**: - The triangle is positioned such that one side is horizontal (the base) and another side is vertical (the height). 2. **Sides and Labels**: - The vertical side is labeled as **H**, representing the height. - The hypotenuse, labeled as **D**, represents the diagonal side of the triangle. - The base of the triangle is labeled with an angle **θ** (theta) between the hypotenuse and the base. 3. **Right Angles**: - At both ends of the hypotenuse, there are right angle markers (squares with numbers 1 and 2), indicating that these are 90-degree angles. - Point 1 is at the base level, and point 2 is at the top of the height. This diagram is useful for explaining concepts such as trigonometric identities, slope, or calculating the length of sides using the Pythagorean theorem.
