With using orbital motion $($PQ$=$PR$+$RQ$)$

A planet of mass $2\mathrm{.}0$ x $10^(24)$kg orbits a star. At point P in the orbit, the planet is moving with a speed $4\mathrm{.}0$km$//$s in the direction shown in the picture. The star $($S$)$ is directly below the point P$.$ The force exerted by the star on the planet at P is $9\mathrm{.}0$ x $10^(23)$N$.$ During a time interval of one

hour, the planet moves from point P to point Q $.$ During this time, the force does not change appreciably in magnitude and direction. Calculate the location of the future point Q and show it

in the picture. Draw all relevant displacements to scale.

$($If you show how to draw the picture properly, thank you!$)$
