You want to design the loop-the-loop toy. The idea is that a ball of mass m=0.01 kg and radius r = 5.0 cm will roll down an inclined track and around the loop without slipping. The ball starts from rest at a height of h meters above the tabletop that supports the whole track. If the radius of the loop is R = 0.25 m, determine the minimum height necessary for the ball to remain in contact with the track during the whole loop-the-loop journey.
Illustrate what is the smallest angle of incidence with respect to the top mirror, such that the laser beam hits the mirrors in each way?
make sure to label the graphs with units and values to indicate any critical points of the ball's motion.
What is the frequency of light that has the wavelength in water of 788 nm if the refractive index for this light is 1.33.
Calculate the velocity of the object for an elapsed time of t=1s. Use the formula v=v0+at, these use the v0,and the value for acceleration you determined in previouse step. PROBLEM:V=Vo+at Vo is 3.8 m/s a=1.2m/s^2
