A stone is thrown from a rooftop at time t = 0 seconds. Its position at timet is given by F(t) = (7t,-31, 19.6 – 4.91²). %3D The origin is at the base of the building, which is standing on flat ground. Distance is measured in meters. The vector i points east, j points north, and k points up. (a) How high is the rooftop? meters. (b) When does the stone hit the ground? seconds. (c) At what point (in R') does the stone hit the ground? (in meters) (d) How fast is the stone moving when it hits the ground? (in meters per second)

If an object is located 20m to the right of the origin at 1:00 PM, and later the object is located 30 m to the left of the origin at 2:00 PM, then the displacement from 1:00 PM to 2:00 PM is what?
An archer fish spies a meal of a grasshopper sitting on a long stalk of grass at the edge of the pond in which he is swimming. The fish is to successfully spit at and strike the grasshopper, which is 0.200 m away horizontally and 0.435 m above his mouth. What angle (in degrees) above the horizontal must he spit? Assume vfy = 0.

He was skiing off a slope inclined at theta = 26.7 degrees below horizontal at a speed of v0=22 m/s. He must clear a gorge and slope on the other side at height h = 14.7 meters below the edge of the higher slope. How do you determine the maximum width of the gorge (in meters) so that he clears it?
A prisoner, 1.80 meters in height, was discharged in consideration due to his advanced in age. In order to receive full pardon, he must run as fast as he can towards the country border 100 meters from the prisoner's position to be totally free. Unknown to the prisoner, he was not meant to be discharged alive, due to the heinous crimes he has committed. An archer with an exceptional accuracy, hidden from the prisoner, was 15 meters behind him. As soon as the prisoner started running at a rate of a = 0.012t, an arrow was released 30 seconds after the prisoner moved from rest, from a 2-meter high at an angle of 30 degrees above horizontal aiming at the middle of his body for a sure kill (neglect air resistance). a. What should be the initial velocity of the arrow if the prisoner was dead before reaching the country border?
