Question

A particle moves along the x axis. Its position is given by the equation

x = 2.5 + 2.6t − 3.5t²

with x in meters and t in seconds.

Expert Solution

Step 1

$P o s i t i o n o f a p a r t i c l e i s g i v e n b y : x = 2.5 + 2.6 t - 3.5 t^{2} V e l o c i t y o f t h e p a r t i c l e i s g i v e n b y : v = \frac{d x (t)}{d t} v = \frac{d (2.5 + 2.6 t - 3.5 t^{2})}{d t} v = 2.6 - 7 t$
