Q4.12Multiple correct
A particle slides down a frictionless parabolic (y = x2) track (A – B – C) starting from rest at P point A (Fig. 4.2). Point B is at the vertex of parabola and point C is at a height less than that of point A. After C, the particle moves freely in air as a projectile. If the particle reaches vo highest point at P, then
This question refers to a figure in the original PDF.
- (a)KE at P = KE at B
- (b)height at P = height at A -x2 -x1 B -xo x
- (c)total energy at P = total energy at A (x = 0)
- (d)time of travel from A to B = time of travel from Fig. 4.2 B to P.
