Question

Yusei is on vacation and is pulling his 22.6-kg suitcase through the airport at a constant speed of 0.461 m/s. He pulls on the strap with 126 N of force at an angle of 38.0° above the horizontal. Determine the normal force experienced by the suitcase.

Answer 1

Yusei is on vacation and is pulling his 22.6-kg suitcase through the airport at a constant speed of 0.461 m/s. He pulls on the strap with 126 N of force at an angle of 38.0° above the horizontal. Determine the normal force experienced by the suitcase.

Solution

Ma = 22.6 kg

Speed = 0.461 m/sec

Force = 125 N

Angle = 38.0°

Normal force = ?

Normal force :-

=> Sin38 + m×a

=> 126×0.61+22.6×9.8

=> 76.86 + 221.48

=> 298.3414

So the normal force = 298.3414
