In an old Lab report, some students reported that in Method I, the Vernier track and block slid together on the table as the block was being pulled. What can be said about the coefficient of the static friction between the block and the track, compared to the track and the table?
Homework Answers
As the block and Vernier track moves together, the frictional force between must be very high as compared to the frictional force between table and track
Hence the coefficient of friction between block and track is higher than that of track and table

TCTIOUN Fan Block A student in a physics lab has a block with a fan attached to it, as shown in the figure above. The fan has a pivot so that the angle e it makes with the horizontal can be adjusted between 0° and 90°. When the fan is pointed horizontally so that 0 0°, the block accelerates from rest along a track, even though there is friction between the block and the track. For the following questions, assume...

17. What is T, and T2 if the pulleys are frictionless and the coefficient of kinetic friction between the block and the table is 0.4, and the coefficient of static friction is 0.5. The table is at 0= 30° above the horizontal. (here you have numbers but you can try this one with variables) M= 3k UK', us 3 kg =M 8 kg =2/3 M

Question 3: In order to determine the force of friction and the coefficient of kinetic friction, you will use Vernier Video Analysis to find the acceleration of the cart. You will use the following video to determine these values. Download the following video and open up Vernier Video Analysis, and then import the video into the program. You need to begin your analysis after the hand is no longer pushing the cart and finish when the cart has come to...
