Question

4.12 A particle slides down a frictionless parabolic
(y = x) track (A - B - C) starting from rest at
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
highest point at P, then
(a) KE at P = KE at B
(b) height at P = height hat A
(c) total energy at P = total energy at A
(d) time of travel from A to B = time of travel from
B to P.
PS: it is an mcq
plz answer the question with proper explanation and plz no faltu Bakwass...

Answer 1

Answer:

A particle slides down a frictionless parabolic (y = x2) track (A-B-C) starting from rest at point A. point B is at the vertex of parabola and point C is at a height less than of point A. after C, the particle moves freely in air as a projectile.
