Question 10 (5 points) Angela has a bucket of mass 2 kg tied to a string. She places a drinking glass of mass 0.5 kg in the bucket. She spins the bucket in a vertical circle of radius 1.5 m. You want to find out how fast she must swing the bucket to keep the glass from falling out. a. Draw the free-body diagram for the glass when it is at the top of the circle. (1 point)A roller coaster starts at the top of a hill of height h, goes down the hill, and does a circular loop of radius /before continuing on. This roller coaster is not attached to the track - it only glides on top of it, so it could fall off at the top of the loop. This section of the roller coaster is shown below. h If the roller coaster starts at the top of the hill with zero velocity, what is the expression for the velocity of the roller coaster at the top of the loop? a. Draw the free-body diagram for the roller coaster at the top of the loop. (1 point)
