Physcis problem?
A stone at the end of a sling is whirled in a vertical circle of radius 1.40 m at a constant speed v0 = 2.20 m/s as in Figure P4.57. The center of the string is 1.50 m above the ground.
(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?
(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?
(c) What is the acceleration of the stone just before it is released at A?
Magnitude (absolute value)______
Direction(choose from below):
(in the direction of v0
downward
toward the center of the circle
upward)
(d) What is the acceleration of the stone just after it is released at A?
Magnitude (absolute value) _______
Direction(choose from below):
(downward
toward the center of the circle
in the direction of v0
upward)
