Homework Statement
A train slows down as it rounds a sharp horizontal turn, slowing from 80.7 km/h to 58.9 km/h in the 12.4 s that it takes to round the bend. The radius of the curve is 165 m. Compute the acceleration at the moment the train speed reaches 58.9 km/h. Assume that it continues to slow down at this time at the same rate.
Magnitude?
Direction? ____° backward (behind the radial line pointing inward)
Homework Equations
a = change in V/ change in T
a = v^2/r
The Attempt at a Solution
I've attempted the equations above and got 42.37 and 0.489 for magnitude, which are both wrong. Can someone please help?
