Question
The car travels at a constant speed
from the bottom A of the dip to the
top B of the hump. If the radius of
curvature of the road at A is pA =
180 m and the car acceleration at A
is 0.4g, determine the car speed v.
If the acceleration at B must be
limited to 0.15g, determine the
minimum radius of curvature pB of
the road at B. *
0.6 m
A
v=23.53ms,
B=467.8 m
None of above
v=26.53ms , B=477.8 m
v=29.53 m/s, B=477.8 m
v=25.53ms , B=457.8 m
B.
