## Tchan 3 years ago PLEASE HELP! PLEASE Josie pulls a bookcase up a ramp to load it into a truck with a force of 54 N. The force moving the bookcase vertically upwards is 27 N as shown in the diagram. Bookcase pulled along a ramp with a force of 54 Newtons and a vertical force of 27 Newtons. What is the angle of the ramp to the ground? 17° 24° 30° 64°

problem? k thnx bai

6. EarthCitizen

wth

7. Tchan

haha i know right

8. Tchan

i am not quite sure what to do here

9. EarthCitizen

no p,$F=mgsin \theta$ like before since it's on an inclined plane

10. Tchan

ha that means? haha can you show the steps?

11. EarthCitizen

$54\sin \theta = 27$

12. EarthCitizen

$\sin \theta =27/54 =0.5$ $\theta = \sin^{-1} 0.5 = 30^{o}$

13. Tchan

okay i think i got it thanks

14. EarthCitizen

no p, God bless
