QUESTION 1
In the case of arbitrary planar curvilinear motion the bestchoice for coordinate system is tangential-normal system
QUESTION 2
Tangential coordinate axis is selected so that its positivedirection is in the direction of motion of particle
QUESTION 3
Normal coordinate is selected so that its positive direction isin
| A. | arbitrary direction |
| B. | direction towards the center of curvature |
| C. | direction opposite to the center of curvature |
QUESTION 4
Normal acceleration is
| A. | inversely proportional to speed |
| B. | proportional to the radius of the curvature |
| C. | inversely proportional to the radius of curvature |
QUESTION 5
Particle moves along curvilinear path with velocity of 30 mi/h.If the radius of curvature at position P is 1,500 ft, what isnormal acceleration of the particle at position P in[ft/s2]?
