please answer all A car is going with a constant tangential acceleration (i.e. increasing speed) in a circular path. As seen from above, the path is counter-clockwise. It crosses the point 'A' at time 0.00, at which point its speed is known. Find the direction of its centripetal acceleration at some time after it crosses the point A:Write your answer in degrees. Given: Speed when it crosses point 'A' - V-3.6 m/s, tangential acceleration a 3.6 m/s2, radius of path...
1. When a point on the edge of a DVD (radius 6.0 cm) moves along an arc of length 120 cm, through what multiple of π rad does the disk turn? 2. With an angular velocity of 3.4π rad/s, how much time is required to complete 11 complete revolutions? 3. The blades of a kitchen blender rotate counterclockwise at 2.2x10^4 rpm (revolutions per minute) a top speed. It takes the blender 2.1 seconds to reach this top speed after being...
Please help with whatever you can! Thanks A car is traveling around a horizontal circular track with radius r- 280 m angle θ~ 26. above the x axis, and the angle θΒ-51, below the x axis. at a constant speed v 19 m/s as shown.

HINT: this problem is about using different coordinate systems to solve kinematics problems! D 4. As rod OA rotates, pin P moves along the curve BCD with a constant speed of 3 m/s (in the counterclockwise direction). The equation for this curve is r = 2/(1+cose). Solve the following for the point shown, when 0 = 1/6 (radians). 0 1m B a) Find dr/dt and do/dt, and express the velocity vector in polar coordinates. b) Find the polar unit vectors...
Please answer correctly and i'll rate a like asap. 1.) A 72-kg woman holds a 9-kg package as she stands within an elevator which briefly accelerates upward at a rate of 0.27g. Determine the force R which the elevator floor exerts on her feet and the lifting force L which she exerts on the package during the acceleration interval. If the elevator support cables suddenly and completely fail, what values would R and L acquire? 2.) The quarter-circular hollow tube...
Please do parts Correct and Quickly. definitely i'll give you A+ rating The XYZ Tile Co. has decided to secure its tile clay from a property owned by John Doe adjacent to the tile plant. The company has made a royalty contract with Mr. Doe according to which Doe's holdings will supply the company's need of 200,000 tons per year for the next 15 years before the clay is exhausted. For the first five years, the company will pay a...
