An asteroid is heading towards us at 11 km/s . scientists decide the best solution is to attach a rocket to the asteroid and fire it to change the trajectory of the asteroid. if the rocket is fired for 8 min, the scientists calculate that the new speed for the asteroid will be 20 km/s and its new trajectory will be at an angle of 29 degrees to its original path. in the process described above, what is the acceleration of the asteroid?
express your answers using two significant figures separated by a comma. assume that the positive x axis is in the direction of the initial motion of the asteroid. the final motion of the asteroid has components in the x and positive y directions only.

Imagine you work as a consultant, and your daily job involves listening to the constructive criticism of others. as part of your job, you must listen to opposing viewpoints to make important decisions. in this activity, you are a consulting dam engineer. you must make a decision about four different dams; should they be repaired, taken down, or left alone? you will listen to contrasting opinions about what should be done with the dams before you make the final decision. as the consulting dam engineer, what do you decide to do with this dam? explain your reasoning. by making your decision, did you support the opinions of the mayor and/or the dam safety official? why or why not?
