It's been a great day of new, frictionless snow. julie starts at the top of the 60∘ slope shown in the figure. at the bottom, a circular arc carries her through a 90∘ turn, and she then launches off a 3.0-m-high ramp. what horizontal distance will she travel before touching down?

She travels approximately 40m before touching down.

Equating inital and final kinetic and potential energies,

m + mg = m + mg

Solving for velocity, at the end of the ramp, v = sqrt()

Now, velocity as she is going off the ramp should be

= sqrt( = 20.8 m/s

Now,  y = + t - g    
            = 3 + 20.8 sin (60) - 4.9
            = 3 + 18.01t - 4.9 
            t = 3.83
Now, distance x = speed*time 
                            =  vt = cos(θ)t
                            = 20.8 * cos(60) * 3.83
                            = 40 m

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
