A particle moves along the same path as in question (4) where the path is d scribed by the expression y = 3x². The projection of the particle along the x-ax varies as 0.2t² ft (where t is in seconds) starting at the origin at t = 0. What ar the acceleration components normal and tangential to the path at t = 2 sec What is the radius of curvature at this point?

A local camera station is tracking a UFO sighting in the evening sky. Find the velocity and acceleration of the UFO in the r and theta directions and then find the velocity and acceleration in the x and y directions. 30 (theta dot)- .043 [rad/see] +.004308 [rad/sec'] 6000 [ft] 283 [ft/sec] 12.011 [f/sec] Y axis Х аxis
