Current Attempt in Progress A Dangerous Ride. You and your exploration team are stuck on a steep slope in the Andes Mountains in Argentina. A deadly winter storm is approaching and you must get down the mountain before the storm hits. Your path leads you around an extremely slippery, horizontal curve with a diameter of 92.0 m and banked at an angle of 40.0° relative to the horizontal. You get the idea to unpack the toboggan that you have been using to haul supplies, load your team upon it, and ride it down the mountain to get enough speed to get around the banked curve. You must be extremely careful, however, not to slide down the bank: at the bottom of the curve is a steep cliff. (a) Neglecting friction and air resistance, what must be the speed of your toboggan in order to get around the curve without sliding up or down its bank? Express your answer in m/s and m.p.h. (b) You will need to climb up the mountain and ride the toboggan down in order to attain the speed you need to safely…
Kindly provide the solution to the following question using the GRASS method. Uniform and Circular Motion (Dynamics Unit): You are an architect designing a roller coaster for a theme park. You plan to construct a track with a loop radius of 75 m. What is the minimum cart speed so that the cart does not fall off the track at the top of the loop? Image attached is a guide on how to use the GRASS method on a question and the other image are the formulas. Please make sure to show all your work.
2 part question A small object of mass of 0.500kg is attached by a 0.870 m-long cord to a pin set into the surface of a frictionless table top.

Task 1: Vector components and free body diagrams Two essential concepts you were learning in the course up to this point were determining the components of a vector and drawing a free body diagram that represents the forces acting on an object. 1. For each of the following, determine the components that make up the resultant vector. a. F = 40 N 25° V-25N 15 E S 15% =25 m/s c. A person throws a ball with an initial velocity of 17 m/s, 65° above the horizontal. -17 m/s 65° X 2. For each of the following draw a free body diagram that includes all of the forces acting on the object described. a. A 40 kg box on a level floor is pulled by a rope attached to the box. The ropes makes an angle of 21° with the horizontal. A force of friction opposes the motion. b. A refrigerator sits on a level floor and a person tries to push on it with a force parallel to the floor. The refrigerator does not move.

Draw a picture of a cart rolling up a ramp. Draw arrows above the cart to show the direction of the velocity and the direction of the acceleration. Choose a coordinate system and include this in your picture. Draw a new picture of a cart rolling down a ramp. Draw arrows above the cart to show the direction of the velocity and the direction of the acceleration. Label your coordinate system. Sketch a graph of the instantaneous acceleration vs. time for the entire motion of the cart as it rolls up and then back down the track after an initial push. Label the instant where the cart reverses its motion near the top of the track. Explain your reasoning. Write down the equation(s) that best represents this graph. If there are constants in your equation, what kinematic quantities do they represent? How would you determine these constants from your graph?
