Use a graphing utility to obtain the path of a projectile launched from the ground (h = 0) at the specified values of θ = 35°, v0 = 300 feet per second. In the exercise, use the graph to determine the maximum height and the time at which the projectile reaches its maximum height. Also use the graph to determine the range of the projectile and the time it hits the ground. Round all answers to the nearest tenth.

A classic physics problem states that if a projectile is shot vertically up into the air with an initial velocity of 146 feet per second from an initial height of 89 feet off the ground, then the height of the projectile, hh, in feet, tt seconds after it's shot is given by the equation:
h=−16t2+146t+89h=-16t2+146t+89

The drawing shows two cars traveling in different directions with different speeds. Their velocities are:
vAG = velocity of car A relative to the Ground = 32.4 m/s, due eastvBG = velocity of car B relative to the Ground = 21.0 m/s, due northThe driver of car B looks out the window and sees car A. What is the velocity (magnitude and direction) of car A as observed by the driver of car B? In other words, what is the velocity vAB of car A relative to car B?
