Theresa is swinging a 4. 0 kg ball on a 1. 2 m long rope with a tangential speed of 1. 8 m/s. What is the centripetal force exerted on the rope? round to the tenths place.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

a=d/t

a="triangle"v/t

explanation:

a = acceleration
