Question

A woman takes her dog rover for a walk on a leash. She pulls on the leash with a force of 30.0 N at an angle of 29° above the horizontal sidewalk. What force is tending to lift Rover vertically off the ground?
Please help I'm stuck.

Answer 1

19.8 N force is tending to lift Rover vertically off the ground.

What is horizontal and vertical component?

The horizontal velocity component ($v_{x}$) describes the influence of the velocity in displacing the projectile horizontally. The vertical velocity component ($v_{y}$) describes the influence of the velocity in displacing the projectile vertically.

According to the question,

The women pulls the dog with a force of 30 N at an angle of  29° from the horizontal.

Horizontal component=  30cos(29°) = 22.2 N

Vertical component = 30sin(29°) = 19.8 N

Therefore,

The horizontal component would tend to make the dog move forward and the vertical component would tend lift it off the ground.

Hence,

19.8 N force is tending to lift Rover vertically off the ground.
