15 Points A 0.1 kg block is released from rest at point A (See diagram), a vertical distance h above the ground.  It slides down an inclined track, around a circular loop of radius 0.5 meters, then up another incline that forms an angle of 30° with the horizontal.  The block slides off the track at a speed of 4.0 m/s at point C, which is at a height of 0.5 meters above the ground.  (Assume the entire track is frictionless) Determine the height of the initial position of the block. Determine the Normal Force acting on the Block at the top of the Loop Determine the Horizontal Distance that the block will land from the edge of the ramp at point C

In a study, participants were asked to evaluate two contradictory theories. If they preferred one theory and subsequently favored evidence that supported it while dismissing evidence against it, this is an example of: 

What is the greatest number of unique keys a perfect B+ Tree with n=3, l=40 and height=2 (has levels 0, 1, 2) can have (Assume unique values are inserted)? Assume 0 based height. A tree with a single root node has a height = 0. n = maximum children a node can have l = maximum keys a leaf node can have

10 Points A toy gun uses a spring with a force constant of 300 N/m to propel a 10.0-g steel ball. If the spring is compressed 7.00 cm and friction is negligible: How much force is needed to compress the spring? To what maximum height can the ball be shot? What is the gun’s maximum range on level ground?

You are a Doctor of Nursing Practice student analyzing the sleep patterns of college students by calculating the number of hours of sleep. You ask the participants to fill out a tool with a Likert-type scale which does not provide any clinical intervention.  What type of study is this? 

In a survey, participants are asked if they support a “90% success rate” versus a “10% failure rate” for a medical procedure. This illustrates:

10 Points The graph shows the force exerted on a tennis ball (mass = 58 grams) as it is in contact with a tennis racquet moving in the positive direction.  What is the final velocity of the ball if it was moving in the negative direction at a speed of 42 m/s.
