You're heading an international effort to save Earth from an asteroid heading toward us at 10 km/skm/s. Your team mounts a rocket on the asteroid and fires it for 10 minmin, after which the asteroid is moving at 24 km/skm/s at 25 ∘∘ to its original path. In a news conference, what do you report for the acceleration imparted to the asteroid? Express your answers in meters per second squared. Enter your answers separated by a comma. Assume that the positive xx axis is in the direction of the initial motion of asteroid and yy axis is perpendicular to it

Please answer the following question(s): 1. The speed of a boat in still water is vá. A river flows with a speed of v₁. The boat travels distance of 19 miles downstream in a river in 1 hour. However, the return journey takes 2 hours. Calculate the vand v₁. Hint: Velocity=displacement/time. Displacement can be positive of neagtive depending on the direction. You will first need to set up the equations by taking into account the resultant velocity of the boat in flowing water. Consider the direction the river is flowing to be positive. Set up two equations, one for the downstream journey and one for the upstream journey, in terms of "v" and "v": Do v" and "v, add or substract downstream to give the resultant downstream velocity? Do v" and "v, add or substract upstream togive the resultant upstream velocity? Use the upstream direction as negative. The resultant upstream velocity should be negative. vb vb Downstream positive Vr Upstream negative Vr
A plane flying at 78.2 m/s [W32°S] takes 42 seconds to change its velocity to 78.2 m/s [S32°E]. a) Solve for the change in velocity of the plane algebraically, resolving vectors into their x- and y-components. b) What was the average acceleration of the plane over this time interval? c) Explain why the speed of the plane didn't change and yet the plane underwent acceleration. Please label sketches with events as well as GRASS and explanations to show your work. Please label triangle sides. Remember to have the magnitude rounded to a reasonable number of sig figs, the unit and the direction (if needed) in your answers.
You are sitting in your car at a red light when you see a zombie standing still 65m in front of your car. You both begin to accelerate towards each other. Your car accelerates at 1.8 m/s^2 and the zombie accelerates at 0.6 m/s^2. How long does it take for you to strike the zombie? Make sure to include a diagram of the physical situation, label known and unknown quantities with units, and coordinate system. Thanks!

Tom Cogwagee Longboat, of the Six Nations of the Grand River, is one of Ontario's best known distance runners. In 1907, he set a new Boston Marathon record, beating all of the previous decade's champions by almost 5 minutes! If he ran the 39.2 km course in 2 hours, 24 minutes and 24 seconds, what was his speed? HINT: we'll need our units to be metres per second - what do you need to convert in the question? 0.221 m/s O 0.272 m/s O 4.52 m/s O 17.5 m/s

On the map, let the +x-axis point east and the +y-axis north. An airplane flies at 880 km/h northwestward direction (i.e., midway between north and west). Find the components of its velocity. Enter the x and y components of the velocity separated by a comma. I understand the quadrant, and origin but not how to then figure components of airplane's velocity. Can you simply get me up to the speed?
