The rod OA rotates in the horizontal plane such that theta equals0.67t^3 radian, and collar B is sliding outward along OA so that r=70t^2 mm. If in both cases t is in seconds, determine the radial acceleration (mm/s^2) of the collar when the collar is 93 mm from O. Round off only on the final answer expressed in 3 decimal places.

A particle moves ccw on a circular path of 400 ft radius. It starts from a fixed point which is horizontally to the right of the center of the path and moves so that s = 10t2 + 20t where s is the arc distance in ft and t is the time in sec. Compute the x and y components of the acceleration at the end of 3 seconds.

Given that r (t) = (3t cos t)j – (3t sin t) k , is the position В. vector of a moving particle, find the following quantities: 1. The velocity, speed, acceleration, and curvature of the particle, 2. The tangential and normal components of acceleration of the particle. B.
The formula v = v2.3r models the maximum safe speed, v, in miles per hour, at which a car can travel on a curved road with radius of curvature r, in feet. A highway crew measures the radius of curvature at an exit ramp on a highway as 470 feet. What is the maximum safe speed? For this problem, round your answer DOWN to the nearest whole number. (Think: Why is this type of rounding appropriate for this scenario?) max safe speed =
