Please short answer. There are three exercises, number 3 is: 3. Make an explanatory paragraph, about kinetic friction and static friction. Please answer the three exercises.

Individual Practice... 1. I went for a walk one day. I walked north 6.0 km at 6.0 km/h and then west 10 km at 5.0 km/hr. (This problem is deceptively easy, so be careful. Begin each part by reviewing the appropriate physical denition.) Determine... a) the total distance of the entire trip 10 m b) the total displacement of the entire trip 'g c) the angle resultant use this equation K \" - . 2. A landscape architect is given a survey of a parcel of land that is shaped like a parallelogram. On the scale drawing the sides of the parcel of land are 8 in. and 10 in., and the angle between these sides measures 75. The architect is planning to build a fence along the longest diagonal. If the scale on the survey is 1 in. = 120 ff... how long will the fence be? The real angle are: 180 - 7 = 1050 1431 O 5 O 3.
