<em>Comment on percentages</em>
The symbol "%" is a shorthand way to write "/100", so 25% = 25/100 = 0.25.
Of course, 100/100 = 100% = 1.
Adding 25% of something to 100% of it gives 125% of it, the original amount multiplied by 125/100 = 1.25.
Calculation of centripetal acceleration(ac):

we can change our speed in terms of m/s

now, we can plug these values


Calculation of tangential acceleration(at):

now, we can plug values

now, we can simplify it

Calculation of resultant acceleration:

now, we can plug values
