As part of a department store display, a model train D runs on a slight incline between the store's up and down escalators. When the train and shoppers pass point A, the train appears to the shopper on the up escalator B to move downward at an angle of 22° with the horizontal, and to a shopper on the down escalator C to move upward at an angle of 23° with the horizontal to travel to the left. Knowing that the speed of the escalators is 3 ft/s, determine the direction (in degrees) of the train. Indicate if it is "up to the right", "up to the left", "down to the right", or "down to the left", along with the angle of inclination from the horizontal. 30° B 30°

One strategy in a snowball fight is to throw a snowball at a high angle over level ground. Then, while your opponent is watching that snowball, you throw a second one at a low angle timed to arrive before or at the same time as the first one. Assume both snowballs are thrown with a speed of 25.0 m/s. The first is thrown at an angle of 70.0 with respect to the horizontal. (a) At what angle should the second snowball be thrown to arrive at the same point as the first? (b) How many seconds later should the second snowball be thrown after the first for both to arrive at the same time?
Lei A = 60.0 cm at 270 measured from the horizontal. Let B = 80.0 cm at some angle . (a) Find the magnitude of A + B as a function of . (b) From the answer to part (a), for what value of does | A + B| take on its maximum value? What is this maximum value? (c) From the answer to pan (a), for what value of does | A + B| take on its minimum value? What is this minimum value? (d) Without reference to the answer to part (a), argue that the answers to each of parts (b) and (c) do or do not make sense.
A science student is riding on a flatcar of a train traveling along a strait, horizontal track at a constant speed of 16ˍm/s. The student throws a ball into the air along a path he judges to make an initial angle of 64° with the horizontal (toward the rear of the car) and to be in line with the track. The student’s professor, who is standing on the ground nearby, observes the ball to rise vertically. With what initial speed does the professor see the ball rise?
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.

The first is throw at an angle of 70.0o with respect to the horizontal. a) At what angle should the second snowball be thrown to arrive at the same point as the first? Assume air resistance is negligible. b) How many seconds later should the second snowball be thrown after the first for both to arrive at the same time?
One strategy in a snowball fight is to throw a snowball at a high angle over level ground. While your opponent is watching this first snowball, you throw a second snowball at a low angle and time it to arrive at the same time as the first. Assume both snowballs are thrown with the same initial speed 20.5 m/s. The first snowball is thrown at an angle of 68◦ above the horizontal. At what angle should you throw the second snowball to make it hit the same point as the first? The acceleration of gravity is 9.8 m/s 2 . Answer in units of ◦ .
Rain is falling vertically downward and you are running for shelter. To keep driest, should you hold your umbrella vertically, tiltedforward, or tilted backward? Explain.
A car is traveling at night along a highway shaped like a parabola with its vertex at the origin. The car starts at a point 100 m west and 100 m north of the origin and travels in an easterly direction. There is a statue located 100 m east and 50 m north of the origin. At what point on the highway will the car’s headlights illuminate the statue?
A pirate ship is rapidly approaching your fort! You bravely station yourself at the mounted cannon but find to your dismay that you have only one cannonball. Not only this, yoour cannon is rusted in place and can only fire at an angle theta = 10.0 degrees up from the horizontal. To prevent a siege on your fort, you must fire your cannon at exactly the correct moment to strike the enemy ship at the base of its mast. You know that your cannon is stationed on a wall a height h = 8.00 m above your target , and that it fires at a speed of v1 = 205 m/s. You will use this information to determine the distance d at which the pirate ship is in your cannon's range. Part 1: Determine the initial vertical velocity v1,y and the initial horizonal velocity v1,x of the cannonball. Part 2: If the cannonball starts its trajectory at a height y1 = h, determine its height y2 at the top of its arc and the time t2 it takes to get there. Part 3: How long will it take for the cannonball to fall from the…
