Reference no: EM13711920

Solve the all parts of following problem:

Problem: A 980-g rock is whirled in a horizontal circle at the end of a 1.4-m-long string.

Part I: If the breaking strength of the string is 160N, what is the minimum angle the string can make with the horizontal?

Part II: At this minimum angle, what's the rock's speed?

I need help to solve the above problem and express your answer to two significant figures and include the appropriate units.
