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?
At t = 0, a particle moving in the xy plane with constant acceleration has a velocity of vi = (3.00 i − 2.00 j) m/s and is at the origin. At t = 2.60 s, the particle's velocity is v = (8.70 i + 3.40 j) m/s. (Round your coefficients to two decimal places.) Find its coordinates at any time t. (Use the following as necessary: t.)
