Bob tries his luck shooting a slingshot! He swings it horizontally over his head before he releases it. If the rock inside the slingshot has a mass of 0.45 [kg], the radius of the rope loop is 0.5 [m] and its speed it 20.0 [m/s], how much force is he swinging the rope with?

the answer is horst.

explanation:

in physical geography and geology, a horst is a raised fault block bounded by normal faults. a horst is a raised block of the earth's crust that has lifted, or has remained stationary, while the land on either side has subsided. the word horst in dutch and german means heap – cognate with english "hurst".
