Question

I'm trying to do this problem for my homework but I just can'tseem to figure it out! Please help by showing it step by step so Ican understand! Thank you. A particle is moving across a straight line said to be the xaxis (on an x vs t graph) Position            t(s)            x(m) A                     0                30 B                      10              52
C                     20              38
D                     30               0
E                      40                -37
F                     50               -53 Find: A. The displacement: B. Average velocity: C. Average speed between points A and F:

Explanation / Answer

(A). The displacement = 30+52+38+0 -37-53                                   = 30 m (B). Average velocity = dispalcement / time                                 = 30 m / 50 s                                 = 0.6 m / s (C). Average speed between points A and F is V = ( 30+52+38+0 +37+53 ) / 50                                                                               =4.2 m / s
