48 The displacement otan object for a round trip between two locations: * [ (2 Points) is always greater than zero is zero is always less than zero 0000 can be greater or less than but not zero If the speed of particle \"A\" is twice that of particle \"\"B the distance particle \"B\" travels in a given interval of time as compared with particle \"A\" is: t (2 Points} 0 twice as great 0 four times as great 0 half as great 0 one-fourth as great 50 The speed y of a car moving on a straight road is given in m/s as a function of time t in seconds by the following equation: v = 4 + 2t^3. What is the acceleration of the car at t = 2 seconds? * (2 Points) O 12m/50 2 16 m/5 * 2 20 m/5*2 24 m/5^239 Which term is a scalar quantity?* Co (2 Points) C distance O displacement O force O weight37 Two balls are thrown vertically upward, one with an initial velocity thrice that of the other. The ball with greater velocity will reach the top of the flight * Co (2 Points) 3x that of the other 1/3 that of the other 6x that of the other O the same as the other34 A baseball struck by a bat leaves the bat at an angle of 400 above the horizontal and is caught by an outfielder 200 m from the plate. If you assume that it is struck and caught at the same height. What was the initial speed of the ball? * (2 Points) O 9.8 m/5 14 m/5 O 45 m/'s O 129 m/s32 Two balls were thrown vertically upward, one with an initial velocity twice that of the other. The ball with greater velocity will reach the maximum height * [ (2 Points) O Twice that of the other O 5x that of the other O Half that of the other O 4x that of the other31 If you throw a stone straight up at 50 m/s, how long will it take for it to come back to your hand where you threw it?* (2 Points) O O 10 5 20 s O 100 s29 Consider two projectiles whose initial position is the same height, y = 5m. Projectile 1 is fired horizontally with initial velocity horizontal speed y = 10 m/s, while Projectile 2 is dropped. How far has Projectile 1 traveled horizontally when it strikes the ground?* (2 Points) O 5m O 10 m O 15 m O 20 m28 Consider two projectiles whose initial position is the same height, y = 5m. Projectile 1 is fired horizontally with initial velocity horizontal speed v = 10 m/s, while Projectile 2 is dropped. Which projectile strikes the ground with the greater velocity? * (2 Points) Projectile 1 O Projectile 2 Both projectiles strike the ground with the same velocity Incomplete information1 If any of three vectors A, B, and Care added in order, and the head of C ends on the tail of A, the resultant of the vectors is (2 Points) O equal to (A^ 2 - B^2 - C^2) O the hypotenuse of a triangle zero O equal to vector C
