A woman at an airport is pulling her 19.0 kg by a strap at an angle of 32 ° above the horizontal as shown in figure Fig. P5.44. She pulls on the strap with a 40.0 N force, and friction is negligible.

Question

(a) What is the acceleration of the suitcase?
(b) What normal force does the ground exert on the suitcase?

Answer 1

figure the vertical and horizontal components of the pulling force.

a=horizonalcomponentpulling force/mass

normal force=mg-verticalcomponentforce
