Chapter 12

A particle is moving along a straight line such that its position is defined by (1020) mm, where I is in seconds. Determine (a) the displacement of the particle during the time interval from 1sto1-5s, (b) the average velocity of the particle during this time interval, and (c) the acceleration when I s.

SOLUTION

3=10+20

(a), 10(1)+20= 30 mm

10(5)² + 20 = 270 mm
