Homework Statement
A train slows down as it rounds a sharp horizontal turn, slowing from
90.0 km/h to 50.0km/h in that 15.0s that it takes to round the bend. The
radius of the curve is 150m. Compute the acceleration at the moment the train
speed reaches 50.0 km/h. Assume that it continues to slow down at this time at
the same rate.
Homework Equations
The Attempt at a Solution
Find the radial and tangential accelerations then get total acceleration. Direction
will be tan-1 of those. I've tried to start but my numbers don't seem to be
right. I've drawn a sketch.
Thanks,
Kevin
