Answer:

9567.333

Explanation:

Taking gravity into consideration, we can calculate all this by a formula:

f1 = m*g = 1400*9.81 = 13734 N.

Just like this we can calculate the centrifugal force using the similar formula:

f2 = m*(v∧2)/r = 1400*(25∧2)/210 = 4166.67 N

Therfore the final answer can be calculated as:

f1-f2 = 13734 - 4166.67 = 9567.333

Goodluck, i hope this helps.
