Question

A child decides to take her cat on a walk, but the cat does not cooperate. The child pulls on the 2.5 kg cat with force of 20 N in a direction that is 30 degrees above horizontal, and the cat resists being pulled forward with a horizontal force of 15 N.

How much force is the child pulling with in thedirection the cat will move?

Expert Solution

Step 1

For cat to move..... Force applied by child in horizonty direction should be greater than the resistance of cat....

Mass of cat = m = 2.5 kg

Fr = 15 N

F = 20 N...

With 30° horizontal....

So Fx = 20 cos(30)

Fy = 20 sin(30)

Also in y direction there are other forces also....
