20 POINTS PLSSS 1: When given a motion graph, how can you tell if it’s a speed graph or acceleration graph?

2: A plane takes 8 hours to fly 5000 km. What is its speed?

Determine the largest intensity w of the uniform loading that can be applied to the frame without causing either the average normal stress or the average shear stress at section b–b to exceed σ=19 mpa and τ=24 mpa, respectively.
