Find the velocity of the particle which follows the following curves (x in m and t in sec) :
(a) x1(t) = 100 + 4 t.
(b) x2(t) = 3 + 4 t.
We will present two methods to solve this problem
These are equation for a straight line. the general form of a straight line equation is
x(t) = c1 + c2 t,
where c2 is the slope of the line.
Sine the velocity is the slope of x(t),
(a) v1(t) = 4 m/sec
(b) v2(t) = 4 m/sec
