A flint-glass prism is made in the shape of a 30 degree-60 degree-90 degree triangle. Red and violet light are incident on the prism at right angle to it's vertical side. The index of refraction n red= 1.66, n violet = 1.70. What angle does each ray make with the horizontal when it emerges from the prism?
A projectile is launched straight up at 59 m/s from a height of 73 m, at the edge of a sheer cliff. The projectile falls, just missing the cliff and hitting the ground below.
About the axis of the rod.ωA ball of mass m is attached by two strings to a vertical rod. The entire system rotates at constant angular velocity.
A 100 g (mass) bouncy ball has a downward velocity of 10 m/s right before hitting the ground. How long was the ball in contact with the ground to the nearest second
The range equation can only be used if the projectile is launched from the ground and returns to the same height as it was fired from. Find the angle of launch which maximizes the range as a function of height
