my friend bob takes a walk at constant 1.2 m/sec for 8.5 min east. then jogs 2.7 m/sec for 6.3 min south. what is the magnitude of bobs total displacement?
would it be 510s*1.2 for one side then 378*2.7 and i then use the quadratic equation or is this the wrong idea?
|dw:1339166795849:dw|
pythagora's would also work.. cosine law would help.. but here angle is 90º so PGT will work
