1.Hold a single coffee filter in your hand. Release it and watch it fall to the ground. Next, nest two filters and release them. Did two filters fall faster, slower, or at the same rate as one filter? What kind of mathematical relationship do you predict will exist between the velocity of fall and the number of filters? 2.If there was no air resistance, how would the rate of fall of a coffee filter compare to the rate of fall...
A small ball has a mass of 2.3 g and a terminal speed of 9.0 m/s. The drag force is of the formbv2 a) How much is the acceleration when the terminal speed is reached? b) Calculate the magnitude of the drag force when the terminal speed is 5. reached c) What is the value of b? g = 9.8 m/s2
Th figure below shows a mass m=1.0 kg which is initially moving with speed v=7.2 m/s at the top of a frictionless hill of height h=4.9 m. It slides down the hill until it encounters a flat section with unknown coefficient of kinetic friction µk. If the object travels a distance D=11.1 m before reaching a speed of v/2, what is the coefficient of kinetic friction µk? (use picture, but first question) Th figure below shows a mass m=1.0 kg...
