- A 2,191 kg roller coaster cart goes 14.97 m/s at the top of a vertical circular loop of 20 m radius. There is no friction. What would the magnitude of the normal force on the cart be when it is moving straight down (20 m from the bottom) in N?N 8. You are riding a roller-coaster going around a vertical loop, on the inside of the loop. If the loop has a radius of 55.0 m, how fast must the cart be moving in order for you to feel 2.75 times as heavy at the bottom of the loop? m/s R 20 MacBook Air N J M K 17 1A roller coaster cart is moving over the top of a circular hill that has a diameter of 56 m. What is the fastest safe speed that the roller cart can go over the top of the hill? (that is, at what speed will the cart begin to lose contact with the track?). Assume a coefficient of friction of 0.7.
- 4. An object of mass m makes a loop-the-loop as shown. When it is upside down at point A, the normal force is found to be 2mg. a) What is the speed of the object at point A in terms of g and R? b) What is the normal force at point B, neglecting any friction of air resistance? Put your answer in terms of m and g. A B5.) Imagine a 5.00 kg mass hanging from a rope on a planet with a value of g=0.500 m/s^2. In addition, there is a spring that goes straight down from the mass to the ground, and the spring has a spring constant of k=20 N/m. The spring has been stretched from its equilibrium position by 4.00 cm. The rope will break if the tension exceeds 5 N. (5a) Draw a free-body diagram for the mass, labeling all forces. (5b) What is the tension in the rope? (5c) The mass is slowly lifted using the rope, so that the spring continues to stretch. How many more centimeters can you stretch the spring before the rope breaks?Wing Loading of = 570 N/m² Co = 0.06 +0.0150₂² The glider was launched at 500 meters altitude. Calculate for mimimum rate of descent in meters per second. (Round off answer with two decimal places, No units, No commas) Answer given: 23554 Which is not true about the effect of altitude? A. Points with the same value of a therefore must have the same glide path angle. B. The drag polar changes with flight speed. C. The glide path angle is independent of altitude and depends solely on the angle of attack.
