3 Question 6 (8 points) A dog is chasing a cat, which is chasing a mouse. All of the animals are moving in one dimension. The mouse is in the lead, moving at 4.31 m/s. The cat is in the middle, moving at 1.12 m/s. The dog is in the back, moving at 4.26 m/s. All velocities are relative to the ground. What is the velocity of the cat from the perspective of the dog? Include negative signs as appropriate....
A dog walking to the right at 1.5m/s spies a cat ahead, and begins chasing the cat with a constant acceleration of 12 m/s. What is the velocity of the dog after running for 3.0 m? Round the answer to two significant digits. Answer using a coordinate system where rightward is positive.

A 27.2 kg dog is running northward at 2.64 m/s , while a 5.85 kg cat is running eastward at 2.74 m/s . Their 75.9 kg owner has the same momentum as the two pets taken together. Find the direction and magnitude of the owner's velocity.
A 19.0 kg dog is running northward at 2.14 m/s , while a 5.08 kg cat is running eastward at 3.26 m/s . Their 71.7 kg owner has the same momentum as the two pets taken together. Find the direction AND magnitude of the owner's velocity.
D Question 8 1 pts An object's velocity in the positive x-direction changes from 2.5 m/s to 8.7 m/s in 3.6 s A force of constant magnitude 18 N is acting on it. What is the object's mass in kg? Enter a number with two digits behind the decimal point.
Average and Instantaneous Velocity A particle moves along the x axis. Its position varies with time acording to the expression x =-4t + 2t2, where x is in meters and t is in seconds. The position-time graph for this motion is shown in the figure. Notice that the particle moves in the negative x direction for the first second of motion, is momentarily at rest at the moment t = 1 s, and moves in the positive x direction at times...
A dog running in an open field has components of velocity vx = 2.7 m/s and vy = -1.4 m/s at time t1 = 11.1 s . For the time interval from t1 = 11.1 s to t2 = 23.1 s , the average acceleration of the dog has magnitude 0.51 m/s2 and direction 31.0 ∘ measured from the +x−axis toward the +y−axis. 1) At time t2 = 23.1 s , what is the x-component of the dog's velocity? 2)...
