Answer:
The aim of layout is both to present information in a logical, coherent way and to make the important elements stand out. An additional, more understated benefit, is that a well-designed layout can make the content easier to understand.
Answer:
Explanation:
The initial kinetic energy will be increased by the loss of potential energy and be decreased by the work of friction.
½mv₁² = ½mv₀² + mgh - Fd
½70v₁² = ½(70)14² + 70(9.8)(30) - 13(440)
v₁ = 24.9112... ≈ 25 m/s
