Question

10 Problem3: It's been a great day of new frictionless snow. Julie starts at the top of the 60 slope shown in the figure below. At the bottom, a circular are carries her through a 90° tum, and she then launches off a 3.0-m-high ramp. a) By using the law of conservation of mechanical energy and kinematics determine how far horizontally is her touchdown point from the end of the ramp? 25 m 90 60° 3.0m

Answer 1

Concept: use the conservation of energy principle to find the speed at bottom portion of the track and then taking downward as positive, use equation of kinematics to find time taken and use time to find the horizontal displacement
