You hold a bucket in one hand in the bucket is a 550 g rock You Swing the bucket so the rock moves
in a vertical de 25 m in diameter

What is the minimum speed the rock must have at the top of the circle it is to always stay in contact with the bottom of the bucket?
Express your answer to two significant figures and include the appropriate units.

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
