A car is travelling around a horizontal circular track with radius r = 270 m. It takes the car t = 66 s to go around the track once. The angle theta A = 19 degrees above the x axis, and the angle theta B = 56 degrees below the x axis. 1) What is the magnitide of the car? 2) What is the x component of the car's velocity when it is at point A? 3) What is the...

1. An 800 kg car travels around the edge of a circular track of radius 400 m. At one point, the car accelerates around the track, increasing its speed from 40 m/s to 60 m/s over the course of 5 s. At the instant that the car reaches 50 m/s find (a) its angular velocity (b) its radial acceleration, (c) the centripetal force acting on the car, (d) the tangential acceleration of the car, and (e) the magnitude of the...

A car is speeding up uniformly at a rate of 0.400 m/s2 while traveling counterclockwise around a circular track of radius 500 m. At the instant the car is moving due north, its speed is 9.00 m/s. What is the magnitude (in m/s2) and direction (in degrees west of north) of the total acceleration of the car at this instant? Use a positive angle for west of north and a negative angle for east of north.

A test car starts from rest on a horizontal circular track of 80 m radius and increase its speed at a uniform rate to reach 100 Km/h in 10 seconds. Determine the magnitude of total acceleration of the car 8 seconds after the start . Rotation of the radially slotted arm is governed by 0-0.21 + 0.02r, where 0 is in radians and t is in seconds. Simultaneously, the power screw in the arm engages the slider B and controls...
