You are riding a bus traveling forward at 34 m/s. You move toward the back of the bus at 2m/s relative to the bus What is your speed relative to the road2 (P.4F, P.2L) PSRC1

I see that an object has is decelerating, what does this tell me about A? A. Nothing at all, what i see has nothing to do with A B. A is a positive C. A is a negative  D. A could be either, depending on the direction of the velocity Can I do the vertical part of a projectile motion problem separately from the horizontal part? A. Always.  Horizontal motion is completely separate from vertical motion though they share time B. Never.  C. Only under very special circumstances

Suppose that the gravitational acceleration on a certain planet is only 3.0 m/s2. A space explorer standing on this planet throws a ball straight upward with an initial velocity of 18 m/s. a. What is the velocity of the ball 4 seconds after it is thrown? b. How much time elapses before the ball reaches the highpoint in its flight?

A flower pot falls from a window that is 50 meters high. When is the speed of the flower pot 10 m/s? A.During the entire time of its fall B.After it has fallen 10 meters C.At the end of the first second of its fall D.At no time is the speed 10 m/s

David is buying a jet boat this summer and spending a lot of time zooming around. One place he plans on going is to the Plate River above Albany, NY. The current is 4 m/s south and the river is 200m wide. the boat will move at 20 m/s at full throttle, his only setting.  A. how quickly will he cross the river if he heads straight across?B. how far downstream will he end up if he does so?C. if he wants to go straight across, what angle upstream should he use?

Huck Finn walks at a speed of 0.60 m/s across his raft (that is, he walks perpendicular to the raft's motion relative to the shore). The raft is traveling down the Mississippi River at a speed of 1.77 m/s relative to the river bank (see the figure (Figure 1)). Figure 10.60 m/s River 1 of 1 Y ▼ Part A What is Huck's velocity (speed and direction) relative to the river bank? Express your answer to three significant figures and include the appropriate units.

4. A ball is shot from a cannon at 50 m/s at an angle of 30° above the horizontal. a. Draw a labeled diagram with all relevant information. Note directions you chose to be +x and +y. b. How far has the ball traveled horizontally when it reaches its highest point in the flight? How high is it at this point? c. What is the speed of the ball at the highest point in its flight?

A hot air balloon flying horizontally at a velocity of 50m/s and at an altitude of 475 meters when one if its sandbags falls off.  A. How long (in seconds) does it take the sand bags to reach the ground? B. What horizontal distance (in meters) will the bag travel before it strikes the ground?

3. The motion of a particle is given by the equations = 2t* -+2t. Solve for the values of velocity (v) and acceleration(a) when t= 2sec. Express velocity in ft/s and acceleration in ft/s². %3D

On the Apollo 14 mission to the moon, astronaut Buzz Aldrin hit a golf ball with a golf club improvised from a tool. The free-fall acceleration on the moon is 1/6 of its value on earth. Suppose he hit the ball with a speed of 29 m/sm/s at an angle 22 ∘∘ above the horizontal.   a. how long was the ball in flight in seconds? b. how far did it travel in meters? c. If there was no air resistance, how much farther would it travel in meters on the moon than on earth?
