Question

usWhich of the following X-Y tables agrees withthe information in this problem?A missile is moving 1810 m/s at a 20.0° angle. It needsto hit a target 29,500 m away in a 65.0° direction in9.20 s. What acceleration must its engine produce?хYB)хYC)хYA)ViVE1700619V;17006191700619<<??V?a??aa?AX12500 | 26700Ax 12500 26700Ax 12500 26700t9.209.20t9.209.20t8.653.15

Answer 1

The given value of the distance at which the target is present is

`d=29500\text{ m}`

The distance along the x-axis is,

`\begin{gathered} d_x=d\cos (65^(\circ)) \\ d_x=29500*\cos (65^(\circ)) \\ d_x=12467 \\ d_x\approx12500\text{ m} \end{gathered}`

As in the given tables, the value of the distance and time 9.2 s is correct in first two only. So, the third one is not the correct option.

From the given question, the value of the acceleration is to be found.

The question mark arrows are on the acceleration is only on the b table.

Hence, Table B agrees with the information in the given situation.
