3. Design a roller coaster that falls down a long ramp and then enters a Loop-D-Loop.

(a) Specify the mass of the roller coaster and the radius of the Loop-D-Loop.

(b) Draw the FBD of the roller coaster at the top of the Loop-D-Loop (with origin and axes). Explicitly state the value of the normal force at that point.

(c) Calculate the speed of the roller coaster at the top of the Loop-D-Loop

. (d) Specify a starting height of the coaster at the top of the ramp that is tall enough to allow the roller coaster to clear the Loop-D-Loop.

(e) Determine how much energy was lost through friction.

A roller coaster enters the bottom of a circular loop with just the right speed such that its speed at the top of the loop momentarily is zero. As the name suggests, the roller coaster is coasting through the loop, that is there is no motor actively propelling the roller coaster. Also, ignore friction. What can you say about the direction of the acceleration of the roller coaster as it is halfway up the loop (in the 3-o-clock position of...

A roller coaster car of mass 800 kg when released from rest at point A (height h above the ground) slides along the track and inside the loop of radius 16.0 m. The car never loses contact with the track. Draw below a free body diagram for the car at the top of the loop.

A stunt rider is traveling clockwise around the inside of a vertical, circular loop of track, riding a motorbike at a constant speed of 16.1m/s. a) Draw a FBD of the bike when its at the very top of the circular track and moving to the right. Neglect air resistance and friction b) Although the bike's speed is constant, its acceleration isn't zero. Explain why, in 1~2 sentences without equations or calculations, starting with a brief definition of acceleration. c)...

Design a "bungee jump" apparatus for adults. A bungee jumper falls from a high platform with two elastic cords tied to the ankles. The jumper falls freely for a while, with the cords slack. Then the jumper falls an additional distance with the cords increasingly tense. Assume that you have cords that are 12 m long, and that the cords stretch in the jump an additional 19 m for a jumper whose mass is 120 kg, the heaviest adult you...
