LAB 3: FORCE EVALUATION Texas A&M University College Station, TX 77843, US. Abstract This lab report will be covering the general concept of static friction and kinetic friction. With the usage of camera and interface with computer we will find out these forces. One will use a small piece of wood (in rectangle shape) with two different surfaces on both sides and that wooden pieces will be dropped from certain angle to get the values of static friction and static kinetic. Along with these...

Question 1 Correct 5.00 points out of 5.00 A 0.200 kg dart is fired horizontally at a speed of 2.75 m / s when it hits a 0.700 kg block ofwood suspended by a string. The nose of the dart sticks into 0.00210 m the wood. Together the dart and block swing upwards from a height of 0.0500 m above a table to 0.128 m above the table. Which of the following is the average force the dart applies to the block during impact? Select one: a. 32.4 N b. 15.1 N c. 1.36 N d. 0.872 N Straighterl...
