SUMMARY

The problem involves calculating the force applied to a suitcase being pulled at a constant speed with a handle angled at 22° above the horizontal. Given the suitcase's weight of 23 kg and a normal force of 170 N, the force of gravity acting on the suitcase is determined to be 183.5 N. By applying the equations of motion for both horizontal and vertical forces, the force applied to the handle is calculated to be 68.68 N.

PREREQUISITES

Homework Statement



A 23 kg suitcase is being pulled with a constant speed by a handle that is at an angle of 22° above the horizontal. If the normal force exerted on the suitcase is 170 N, what is the force F applied to the handle?

Homework Equations





The Attempt at a Solution


Aight here is another one i am having trouble with! Again any help or suggestions would be great :)

I drew out a diagram. My plan was to solve Force applied to handle by solving two equations (horiztonal and vertical forces)

1) the sum of Forces (x) = Force applied - Force (weight) = 0
2) the sum of Forces (y) = Fnormal -Force(weight)

1) Force applied - sin 22 F(weight) = 0
2) 170 - cos 22 F(weight) = 0
sovling i get force (weight) = 183.5 N
Plugging into the equation for 1
Force applied - 0.3746 (183.5N) = 0
Force applied = 68.68 N

Any help with this one on strategy or how to solve this? thanks so much

What incline? Although the problem is not completely clear, it appears that the suitcase is being pulled along a level surface with the handle raised 22 degrees above the horizontal.
