#4. A vase was placed on the coffee table. Thecoefficient of static friction between the vase and the table is0.3689, whereas the coefficient of kinetic friction is 0.1339. Thevase weighs 1.0707kg. A cat decided to redecorate the room bypushing the vase off the table. As the cat pushes the vase with itspaw, the vase moves. Then, the cat maintains a constant appliedforce of 7.37N on the vase in the positive x-direction. What is theacceleration of the vase in the x-direction during the time whenthe vase is moving?
#6. A student has two springs. Spring 1 is twice themass of spring 2. The student first puts spring 1 into a masslesspouch and suspends it from spring 2. Spring extension was noted tobe 12.69cm. Then, they put spring 2 into a massless pouch andsuspend it from spring 1. Spring extension was noted to be16.42cm.
What is the ratio of k1/k2?
