Question

A 22 kg bag is being pulled across the floor by a tourist with the force of 50N. The force applied on the handle forms an angle of 30 degrees from the horizontal A. What is the acceleration of the bag? B. How much force is exerted by the floor on the bag if friction is neglected?

Answer 1

horizontal component of force

= F cos 30

= 50(sqrt(2)/2)

= 50*0.707

= 35.4 N

A.

a = F/m = 35.4/22

a = 1.6 m/s

B.

zero, since the floor is frictionless
