A cheetah can go from rest to a speed of 26.8 m/s in 3s. What is the cheetah’s average speed in m/s2?

Honestly "global warming" may be a slight possiblity, however they called it "climate change" because its not real, in fact we had one of our coldest days here not too long ago, and the "issues" with this subject is a blindfold for actual problems.

Is this a question of an answer

Ray 2 should cross through the focal point on the right side of the lens.
