Adog chasing a cat has 0.55 times the kinetic energy of the cat, which has 0.45 times the weight of the dog. the dog speeds up by 0.91 m/s and then has the same kinetic energy as the cat. what was the original difference in speed of the dog and cat? in other words, what is v_sub_cat - v_sub_dog initially (before the dog speeds up)?

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
