- You walk 10 m [E 30o N]. What are the horizontal and vertical components of your displacement, respectively? Drawthe diagram as well.I took 2.28km and converted it to 2280 meters then divided by 3200 and ended up with .71m/s but it keeps saying that its incorrect. Im not sure where I keep messing up. John walks 1.80 kmkm north, then turns right and walks 1.40 kmkm east. His speed is 1.60 m/sm/sduring the entire stroll. What is the magnitude of his displacement, from beginning to end? (2.28) If Jane starts at the same time and place as John, but walks in a straight line to the endpoint of John's stroll, at what speed should she walk if she wants to arrive at the endpoint just when John does?Kinematic Equation Bad Jimmy is at the top of the Centerfor the Sciences (30 m). He throws aball straight upward with a speed of22 m/s.a) How high does the ball go?b) What is the ball’s velocity when itpasses Jimmy on the way down?c) How long will it take to hit the groundfrom when Jimmy threw it?d) What is the ball’s velocity when it hitsthe ground?
- A scooter begins at rest at t0=0 seconds. The scooters starts moving, and eventually covers a distance d= 651m, in a time tf= 104 seconds. In a coordinate system with north being the positive x-direction, the scooter's motion is in the northern direction. What wa the scooter's average speed, during this time period, in meters per second? What was the scooters displacement in the northern direction during this person, in meters? What was the scooter's average velocity in the northern direction, in this period in meters per second? If the scooter's final velocity at tf was 12 m/s, what was the scooter's average acceleration in the northern direction, during this period in m/s%^2?I'm not sure how to solve this! I tried and got 1.3 / 2.4 seconds. Am i right? Could you explain how to do it if i'm not? Cheers ! In a classic Seinfeld episode, Jerry tosses a loaf of bread (a marble rye) straight upward to his friend George who is leaning out of a third-story window. If the loaf of bread leaves Jerry's hand at a height of 1 m with an initial velocity of 18 m/sec, write an equation for the vertical position of the bread s (in meters) t seconds after release. How long will it take the bread to reach George if he catches the bread on the way up at a height of 16 m? Round to the nearest tenth of a second.Dwight decides to race around the perimeter of the Scranton business parkin an effort to beat another employee’s best running time.

- In a total time of 3.0 minutes, a duck on a pond paddles 31 m [N33oE] and then paddlesanother 57 m [E28oS]. Solve for the displacement graphically (with a ruler andprotractor) and then answer the questions. Using the displacement you determined from your graph, what was the duck’s average velocityfor the trip? What total distance did the duck travel? What was the average speed of the duck for the whole trip?Answer the ff: 1. DISTANCE VS. DISPLACEMENT: The rescuers walks 20 km west, then 30 km north, then 15 km west, then 10 km north to locate the victims of the landslide. What is the rescuers TOTAL DISTANCE? What is the rescuers TOTAL DISPLACEMENT? 2. SPEED VS. VELOCITY: Man Naki holds a record of 20 s for the men’s 200-m race at the SEA games. What was his SPEED? 3.ACCELERATION: A car accelerates at a rate of 3.0 m/s². If its original speed is 8.0 m/s, how many seconds will it take the car to reach a final speed of 25.0 m/s?An object is moving in the positive direction along thex - axis. Sketch plots of the object’s position vs. time and velocityvs. time if (a) its speed is constant, (b) it’s speeding up ata constant rate, and (c) it’s slowing down at a constant rate.

A.What is the distance traveled? B. Average speed ? C. Displacement @ end of trip ? D. Average velocity and direction if any ? Can you show me how to solve this please. ThanksA fox is chasing a bunny. The bunny is initially hopping east at 6 m/s when it first sees the fox. Over the next half second the bunny changes its velocity to west at 12 m/s and escapes. What was the bunny's average acceleration (magnitude and direction) during this half-second interval?m/s2 ?
