Acar in an amusement park ride rolls without friction around a track (fig. p7.42). the hb car starts from rest at point a at a cr height h above the bottom of the loop. treat the car as a particle. (a) what is the minimum value of h (in terms of r) such that the car moves around the loop without falling off at the top (point b)

Explanation:

Given that

Height = h

Radius = R

From energy conservation

At point B

The minimum speed to complete the   the circle

So the kinetic energy at point B

Without falling off at the top (point B)

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )

think its the third option
