G A 1.20-kg ball is tied to a 1.20-m long string is being spun in a vertical circle at a constant speed and with a period of 1.60 is. What is the maximum tension in the string

T = 17.42 N

Explanation:

angular velocity(ω) can be calculated from the expression:

=

Since T = 1.60

Then ω =

ω = 3.930 rad/s

Maximum tension of the string would be at the lowest point of the circle which can be written as:

T - mg = mrω ²

T = mg + mrω ²

T = m ( g + rω ²)

T = 1.2(9.8 + 1.20×3.930)

T = 17.4192 N

T = 17.42 N
