Find the velocity and acceleration vectors, the speed ds dt , as well as the tangential and normal components of acceleration for the motion described by R = t i + ln t j for t > . 5. For the curve R = ( tt 3 / 3) ,t 2 ,t + t 3 / 3), nd (a) the unit tangent and normal vectors T ( t ) and N ( t ) at any point, (b) Now nd the curvature ( t ), (c) Find the binormal B ( t ) and the torsion ( t ), (d) Find the length of the arc of the curve cut o between the planes z = 0 and z = 12. 1...
