Answer #1

Answer:

Yes it is possible.

Minimum speed, , where r is the radius.

To calculate minimum speed we need only radius value of the vertical circle

Explanation:

Yes it is possible.

Centripetal acceleration is given by the expression,  

Centripetal force on the body is given by the expression.

The weight of the body is given by, W = mg

The maximum chance of spilling water from bucket is when the bucket is on the top of vertical circle.

So we have,

So to calculate minimum speed we need only radius value of the vertical circle.

PART A) Consider a sea lion swimming horizontally in 20C sea water. It is neutrally buoyant. Its mass is 200kg, body surface area 2.1 m2, and drag coefficient Co= 0.0038. After accelerating from rest for a while (about half minute or so), the animal reaches a state of terminal velocity Uterm of 1.1 m/.s. Calculate the drag and the thrust forces at that moment. PART B) The sea lion studied in the previous question is now vertically diving. It is...

The hill is covered in gravel so that the truck's wheels will slide up the hill instead of rolling up the hill. The coefficient of kinetic friction between the tires and the gravel is ?k. This design has a spring at the top of the ramp that will help to stop the trucks. This spring is located at height h. The spring will compress until the truck stops, and then a latch will keep the spring from decompressing (stretching back...
