Atrain slows down as it rounds a sharp horizontal turn, going from 92.0 km/h to 54.0 km/h in the 16.0 s that it takes to round the bend. the radius of the curve is 130 m. compute the acceleration at the moment the train speed reaches 54.0 km/h. assume the train continues to slow down at this time at the same rate.

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
