What speed is a car going if it takes 2 hours to go 80 miles?

A 150-if object takes 1.5 minutes to travel s 2,500-meter straight path. It begins the trip traveling 120 m/s and decelerates to a velocity of 20 m/s. What was it's acceleration?

A light beam is incident on a piece of fluorite (n = 1.434) at the Brewster's angle. (a) Find the value of Brewster's angle. ° (b) Find the angle of refraction for the transmitted ray.

Since that is not far enough, you consult a friend who calculates (correctly) the minimum speed needed as vmin = 11068 m/s.
