Don't you need The sum of time to calculate speed.

This is the question in my book

A horizontal force of 280 N is exerted on a 2.0 kg discus as it rotated uniformly in a horizontal circle (at arms length) of radius 1.00 m. Calculate the speed of the discus.

I am not he smartest person around but I just for the life of me can not figure how to get the time. am I suppost to assume it.

Thanks
