Suppose that an object travels from one point in space to another. Make a comparison between the magnitude of the displacement and the distance traveled by this object. a. The displacement is either greater than or equal to the distance traveled. b. The displacement can be either greater than, smaller than, or equal to the distance traveled. c. The displacement is always equal to the distance traveled. d. The displacement is either less than or equal to the distance traveled.

An FBI Tactical Operations Team agent uses a high tech sling shot to launch an object from the roof of Building A. She hopes that the object will land on the roof of Building B. There is a 5.00 m wide alley between the two buildings, as shown in the figure. At the instant of its launch, the object has an initial velocity of 6.72 m/s directed 30 degrees above the horizontal. At the instant of its launch, the object is located 0.400 m above the roof of Building A, at a horizontal distance of 0.500 m from the edge of Building A, and 2.00 m above the level of the roof of Building B, as shown in the Figure. Treat the object as a point g = 9.80m 2. particle. Assume that air resistance is negligible, although it would not be. Assume that The near side of Building B 30° 0.400 m | 2.00 m b.500 m 5.00 m Alley 1. How much time does it take the object to reach the highest point in its trajectory? A. 0.594 s. B. 0.686 s. C. 0.859 s. D. 0.343 s. E. 0.561 s. 2. At the instant when the object passes…

C.The direction of the arrow shows the direction of the vector. D. All of the above.   2) Which of the following is the equilibriant of the velocity equivalent to 50kph, 40 degrees S of W? A. 0.28 km B. 0.34 km C. 0.42 km D. 0.66 km

QUESTION 5 Which of the following is not being described by a vector? a. A car travels at a constant speed of 20 m/s due east. b. A camper sees lightning strike 600 m away. C. A spaceship travels in a straight line from the earth to the moon. d. The position of a ship relative to an observer in a lighthouse is 3.0 miles at 37° N of E. e. The acceleration due to gravity acting on a falling brick is 9.81 m/s verticallky downward.

QUESTION 2 Which of the following is an accurate statement? O A. It is possible to add a scalar quantity to a vector. O B. Even though two vectors have unequal magnitudes, it is possible that their vector sum is zero. OC. Rotating a vector about an axis passing through the tip of the vector does not change the vector. OD. The magnitude of a vector is independent of the coordinate system used. O E. The magnitude of a vector can be zero even though one of its components is not zero.

Classify each quantity as a scalar quantity or vector quantity. Answer choices may be used more than once. 1. average velocity 2. distance 3. position 4. speed 5. displacement

An object moves along the xy-plane. At some instant, its velocity and acceleration are - (3 m/s) } , ā = (0.5 m/s²) î – (0.2 m/s²) j. At this instant, the object is 7. = A. speeding up and following a curved path. B. speeding up and moving in a straight line. C. slowing down and following a curved path. D. slowing down and moving in a straight line. E. none of these.

4. Swims across Lake Erie are officially sanctioned by the Lake Erie Open Water Swimming Association. Your friend on the swim team wants to swim across the lake. The plan is that your friend will swim to Presque Isle starting at a location at Long Point, Ontario which is 24 miles due north of Presque Isle. You will be navigating a boat with a GPS. Your friend can maintain a speed of 1.80 mph in still water. All during the swim you observe that objects drifting in the water are moving at 0.70 mph to the east due to the current. a. What bearing should you maintain? That is what direction should you point the boat to reach Presque Isle? Give your answer relative to a compass direction (i.e., 30° north of west). Hint, you want your net velocity vector to be straight south. b. How long did it take your friend to swim across Lake Erie? c. What is the addition amount of time that your friend will need to swim compared to if there was no current (assume your friend swims at a constant rate)?

3. A tennis ball is thrown up in the air. It's height is given by h(t) = -5t2 + 23t + 2, where h(t) is in meters and t is in seconds. Use technology to answer: a.) What is the max height of the tennis ball? When does it occur? b.) How long was the tennis ball in the air?
