- Find the x component of the vector described by "Ground control observes that the plane flies with speed 150 m/s at 40.0 degrees south of wesť"? Give your answer in m/s. Assume positive x points toward the east. Your Answer: Answer unitsA motorcycle is traveling up one side of a hill and down the other side. The crest of the hill is a circular arc with a radius of 66.4 m. Determine the maximum speed that the cycle can have while moving over the crest without losing contact with the road. V = iYou fly 20.0 km in a straight line in still air a direction 35° south of west. Find the distances in kilometers you would have to fly first in a direction 45° south of west and then in a direction 45° west of north. These are the components of the displacement along a different set of axes — one rotated 45°. ______km 45° south of west ______km 45° west of north

Select the case that identifies the puck(s) experiencing equilibrium. II O A. I and II only O B. || only OC.I and III only O D.I only O E. I, II, and IIYou have put a sonar device at the top of a frictionless inclined plane, as shown in the diagram below. That device allows you to measure the distance an object is from the device, as well as the speed and the acceleration of that object. If we decide that the origin (h = 0) is at the sonar device, we want to know what the height change is as we slide down the incline. 0 For an angle below the horizontal of 6.46, we see that our object has slid a distance 1.13 m, as measured along the incline itself. Calculate the height change in meters - and report your answer as a negative number. (This value would be useful for calculating the change in gravitational potential energy, as we will do in the lab.) h=o 10% O i 26 QUATU 99+ hp X 55 83°F 3:11 PM 10/16/2022 Ctrl 0A pickup truck weighing 2500 kg travels at a constant speed of 19m/s around a circular track.

- Solve the following problem using scalar components and use kramer's rule to solve the resulting system of equationsDuring WWI, the Germans had a gun called Big Bertha that was used to shell Paris. The initial velocity of the shell was 1700 m/s at an angle of 55° above the horizontal. Assume it returns to the same height as released. Ignore air resistance. 1. Find the total time in the air for the shell. 2. How far away did the shell hit? 3. Find the shell's velocity at the apex. 4. Find the horizontal and vertical velocity components just when the shell strikes the ground.Dynamics Help! If a baseball player throws a ball a horizontal distance of 100 m in 4 seconds at 45° latitude, by how much is it deflected laterally if he throws toward the east? a) Starting from the appropriate component either du/dt, dv/dt, or dw/dt find an expression for v (no numbers just the variables) b) Find an expression for y (again no numbers, find the equation c) Calculate the actual meridional deflection using the appropriate numbers given in the problem and explain or describe in words what this number means (specific direction)
