1. The problem statement, all variables and given/known data A machaine part moves in a straight line with SHM. At positons 15mm and 20mm from the center of oscillation it has velocitys 2 m/s and 1 m/s respectively. find the amplitude and period of the motion. and the shortest time taken for the part to travel between these 2 positions. 2. Relevant equations angular v= velocity * radius A=Xcos(Angular v*time) 2pi*frequency= angular v Period= 1/frequency 3. The attempt at a solution i have no idea.. its difficult for me to think of anything to help me find angular v ot frequency.
