Mr. Barcena reached a top speed of 5m/s in 2 seconds from rest, what was his average acceleration including units? correct answer is not here
.25
OO00
5.2
2.5

Explanation:

The equation for acceleration is

where vf is the final velocity and v0 is the initial velocity. Filling in:

so

a = 2.5 m/s/s

b would be the answer

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
