26. 

A boat is traveling along a circular path having a radius of 20 m. Determine the magnitude of the boat's acceleration if at a given instant the boat's speed is v = 5 m/s and the rate of increase in speed is v = 2 m/s2.

[A]. a = 2.00 m/s2
[B]. a = 2.36 m/s2
[C]. a = 1.25 m/s2
[D]. a = 12.50 m/s2

Answer: Option B

Explanation:

No answer description available for this question.

v^2/r = 25/20 = 1.25.

dt/dv = vt = 2.

Square root of vn^2+vt^2 = 2.36.
