An object moving with uniform acceleration has a velocity of 10.0 cm/s in the positive x-direction when its x-coordinate is 2.94 cm. if its x-coordinate 2.05 s later is −5.00 cm, what is its acceleration?

  concave means having an outline or surface that curves inward like the interior of a circle or sphere. so the mirror curves inward.

Amicroscope, because these cells are so small that you would not be able to see them, or what they attack without it.

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.
