An amusement park ride consists of a car which is attached to the cable OA. The car rotates in a horizontal circular path and is brought to a speed of 7 ft/s when r = 16 ft. The cable is then pulled in at the constant rate of 1 ft/s. Determine the speed of the car in 4.6 s.

Car A is traveling at the constant speed of 45 km/h as it rounds the circular curve of radius r = 380 m and at the instant represented is at the position 0 = 40°. Car B is traveling at the constant speed of 54 km/h and passes the center of the circle at this same instant. Car A is located with respect to car B by polar coordinates r and with the pole moving with B. For this instant determine VA/B and the values of r and as measured by an observer in car B. Answers: VA/B = r = 0 = i i 8 m/s m/s rad/s B

4. Starting from rest, the motorboat travels around the circular path, p= 50-m, at a speed v = 0.8t m/s, where 't' is in seconds. Determine the magnitudes of the boat's velocity and acceleration when it has p- S0m traveled 20-m.

Car A is traveling on the circular road at the constant speed of vå = 60 km/h. At the instant shown, the speed of car B on the overpass is VB = 80 km/h, and it is decreasing at the rate of 1.6 m/s². Find the relative velocity and acceleration vectors (VB/A, aB/A) at this instant. A 400 m 40° VB B onders X I need a clear answer by hand, not by keyboard | dybala

At the instant shown, cars A and B are travelling at the speeds shown. If B is accelerating at 1200 mi/h2 while A maintains a constant speed, determine the magnitude of the velocity and acceleration of B with respect to A. Car B moves along the curve having a radius of curvature of 0.7mi.  show all the steps in the solution please

A race car enters the circular portion of a track that has a radius of 65 m. When the car enters the curve at point P, it is traveling with a speed of 120 km/h that is increasing at 5 m/s2. Three seconds later, determine the x and y components of velocity and acceleration of the car.    The x component of the total acceleration is m/s2.?   The y component of the total acceleration is – m/s2.?   The x component of the linear velocity is – m/s.?   The y component of the linear velocity is – m/s.?   Note: please show step by step solution. Hence, double check the solution. For correction purposes!. I require  handwritten working out please!. Kindly, please meticulously, check the image for conceptual understanding and for extra information purposes!. Also questions here I post, I receive wrong answers from them on a regular basis!!. Please go through the question and working out step by step when you finish them!!. Appreciate your time!.
