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. 

What is the acceleration of the cat?

Expert Solution
Step 1

Write the given values with suitable variables.

m=2.5 kgF=20 Nθ=30°Fr=15 N

Here, m denotes the mass, F denotes the applied force, θ denotes the angle of the applied force above the horizontal, and Fr denotes the resistive force.
