Question

Help! An asteroid is heading towards us at 10 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 21 km/s and its new trajectory will be at an angle of 25° to its
original path.
Part A
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 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.

Expert Solution

Step 1

Given data:

$\begin{array}{l} u_{x} = 10 km/s \\ u_{y} = 0 m/s \\ v_{x} = (21 km/s) \cos 25 ° \\ v_{y} = (21 km/s) \sin 25 ° \\ t = 8 min \end{array}$

Here, u_x is the initial velocity along the x-direction, u_y is the initial velocity along the y-direction, v_x is the final velocity along the x-direction, v_y is the final velocity along the y-direction, and t is the time.
