Transcribed Image Text:Examples 7
A particle moves in a straight line with a constant acceleration of -4 ft/s2 for 6 s, zero
acceleration for the next 4 s, and a constant acceleration of +4 ft/s2 for the next 4 s. Knowing
that the particle starts from the origin and that its velocity is -8 ft/s during the zero-acceleration
time interval, (a) construct the v-t and x-t curves for 0 st s 14 s, (b) determine the position
and the velocity of the particle and the total distance traveled when t = 14 s.
