Question
In the figure below, a 1.47 kg ball is connected by means of two massless strings to a vertical, rotating rod. The strings are tied to the rod and are taut. The tension in the upper string is 36 N.
(a) What is the tension in the lower string?
N
(b) What is the speed of the ball?
m/s
(c) What is the magnitude of the net force net on the ball?
N
(d) What is the direction of net? (0? means radially inwards.)
?
Explanation / Answer
balance the vertical forces; 36sin30 =mg+T sin30 ; 18-1.47*9.8 = T/2; T = 7.188 N --------------->ANSWER of a) b) the velocity with which the rod is rotated is not mentioned..it only determines the speed of the ball and other c) d) parts..please provide that
