Position, Displacement and Velocity 13. A balloon drifts 140 m toward the west in 45 s; then the wind suddenly changes and the balloon flies 90 m toward the east in the next 25 s. a. What distance did it travel during the first 45 s? b. What distance did it travel during the next 25 s? c. What total distance did it travel? d. What was its average speed during the first 45 s? e. What was its average speed during the next 25 s? f. What was its average speed for the entire trip? g. What was its displacement during the first 45 s? h. What was its displacement during the next 25 s? i. What was its total displacement?

The motion of a bicycle rider moving in a straight line is shown in the graph below.At what time interval do the acceleration points opposite relative to the velocity vector?

Assume that an MX missile goes from rest to a suborbital velocity of 9.50 km/s in 50.0 s (the actual speed and time are classified). What is its average acceleration in m/s2?  What is its average acceleration in multiples of g?

can  you please help me really quick!! thank you i need it in less than 10 minutes

2A) starts from rest and accelerates continuously at a rate of 4.14 m/s² when the rocket is lit, what is the velocity (both magnitude and direction) of the toy car when it reaches the edge of the cliff? Suppose you place your toy car on flat ground 7.30 m away from a tall cliff. If your toy car

Acceleration is positive if.. A) the object is speeding up only  B) the object is slowing down C) the instantaneous velocity is in the positive direction D) the acceleration vector is pointing in the direction of the positive coordinate axis

when an object is speeding up what must be the direction of the acceleration relative to the direction of the objects velocity

15. Your car is traveling behind a jeep. Both are moving at the same speed, so the velocity of the jeep relative to you is zero. A spare tire is strapped to the back of the jeep. Suddenly the strap brcaks, and the tire falls off the jeep. Will your car hit the spare tire before the tire hits the road? Assume that air resistance is absent. (a) Yes. As long as the car doesn't slow down, it will hit the tire. (b) No. The car will not hit the tire before the tire hits the ground, no matter how close you are to the jeep. (c) If the tire falls from a great enough height, the car will hit the tire. (d) If the car is far enough behind the jeep, the car will not hit the tire. 16. The drawing shows two cars traveling in different directions with different speeds. Their velocities are: VAG = velocity of car A relative to the Ground = 27.0 m/s, due east VuG = velocity of car B relative to the Ground = 21.0 m/s, due north The passenger of car B looks out the window and sees car A.
