Dominic is the star discus thrower on South's varsity track and field team. In last year's regional competition, Dominic whirled the 1.6 kg discus in a circle with a radius of 1.1m, ultimately reaching a speed of 52 m/s before launch. Determine the net force acting upon the discus in the moments before launch.

The net force is 3933.1 N

Explanation:

Centripetal force (F) = mv^2/r

m is the mass of the discus = 1.6 kg

v is the speed of the discus = 52 m/s

r is the radius of the circle = 1.1 m

F = 1.6*52^2/1.1 = 3933.1 N
