2.4.13. [Level 2] A particle P is moving along a curve defined by y = ax², where a = 6 ft ¹.y = bx, b= 12 s-¹. Determine where along the curve P's speeds in the i and j directions are equal in magnitude, and calculate the normal and tangential acceleration at that point. L

Your answer is partially correct. A train at a constant 53.0 km/h moves east for 49.0 min, then in a direction 52.0° east of due north for 29.0 min, and then west for 59.0 min. What are the (a) magnitude and (b) angle (relative to east) of its average velocity during this trip?

Initially (at t=0 s) a weather balloon is at x = 0 and at time t (seconds) its horizontal velocity component is 0,2t m/s. The equation of its path is y = 0,2x² m. (a) Calculate the magnitude and direction of its velocity at time t = 10 s. (b) Calculate the radius of curvature at x = 10 m as well as the magnitude of the normal directed acceleration component an there. (c) Assume the acceleration a = 2,4 m/s² and the magnitude of the normal component an 0,4 m/s². Calculate the tangential component at.
