Now we are going to look at a classic example of projectile motion: a bullet fired from a gun. A paintball is fired horizontally at a speed of 75.0 m/s from a point 1.50 m above the ground. The ball misses its target and hits the ground some distance away. (a) For how many seconds is the ball in the air? (b) Find the maximum horizontal displacement (which we’ll call the range of the ball). Ignore air resistance.

Let v1, v2, w be three linearly independent vectors in r 3 . that is, they do not all lie on the same plane. for each of the following (infinite) set of vectors, carefully sketch it in r 3 , and determine whether or not it is a vector space (i.e., a subspace of r 3 ). explain your reasoning

You are driving directly behind a pickup truck, going at the same speed as the truck. a crate falls from the bed of the truck to the road. (a) will your car hit the crate before the crate hits the road if you neither brake nor swerve? (b) during the fall, is the horizontal speed of the crate more than, less than, or the same as that of the truck?
