A small object begins a free-fall from a height of ?=87.5 mH=87.5 m at ?0=0 st0=0 s. After τ=2.25 sτ=2.25 s, a second small object is launched vertically up from the ground with an initial velocity of ?0=41.4 m/sv0=41.4 m/s. At what height from the ground will the two objects first meet?

An object is initially traveling at a velocity of 12 m/s. It then begins to change it’s velocity according to the function ?=2.5?+3? v = 2 . 5 s + 3 a , where v is the velocity of the object, s is the objects position, and a is the acceleration. Determine the velocity of the object 30 meters after the velocity begins to change. (17.5 m/s)
