Aramp leading to the entrance of a building is inclied upward at an angle of 7 degree. a suitcase is to be pulled up the ramp by a handle that makes an angle of 35 degree with the horizontal. how mch force must be applied in the direction of the handle so that the component of the force parallel to the ramp is 50 lbs?

Explanation:

The angle of the handle relative to the horizontal is 35°.  The angle of the ramp to the horizontal is 7°.  So the angle of the handle relative to the ramp is 28°.

cos 28° = 50 / F

F = 50 / cos 28°

F = 56.6 lbs

this means that the temperature of both substances will be equal

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
