Homework Statement
A stone at the end of a sling is whirled in a vertical circle of radius 1.00 m at a constant speed vi = 2.40 m/s as in Figure P4.57. The center of the string is 1.50 m above the ground.

I solved these:
(a) What is the range of the stone if it is released when the sling is inclined at 30.0° with the horizontal at A?
1.05577 m
(c) What is the acceleration of the stone just before it is released at A?
Magnitude
5.76 m/s^2
(d) What is the acceleration of the stone just after it is released at A?
Magnitude
9.81 m/s^2
Homework Equations
(b) What is the range of the stone if it is released when the sling is inclined at 30.0° with the horizontal at B?
The Attempt at a Solution
I've tried doing it the same way I did part a. I used
x(t) = x_o+v_o(t)
and
y(t) = y_o+v_o(t)+(.5)(9.8)(t^2)
it didn't work and I've tried everything that I had in my notes.
