Question

5. A position-time graph for a particle moving along the x axis is shown in Figure P2.5. (a) Find the average velocity in the time interval - 1.50 s to - 4.00. (b) Determine the instantaneous velocity in i- 2.00 s by measuring the slope of the tangent line shown in the graph. (C) At what value of t is the velocity zero?

Answer 1

(a) $v_{avr}=\frac{2-8}{4-1.5}=-2.4(m/s)$

(b) $v=-\frac{13}{3.5}=-3.71(m/s)$

(c) At $t=4(s)$
