1. A small ball moves in a horizontal circle inside a frictionless hemispherical bowl. The normal reaction force N makes an angle θ to the horizontal. 2. A skier of mass 65 kg starts from rest at point A, 50 m above level ground. When passing point B, 20 m above ground, 24% of gravitational potential energy is converted to kinetic energy, giving the skier a velocity of 12 m/s. 3. The hill has a circular shape of radius 20 m at point B. Calculations show that the centripetal force and acceleration requir
