Question

The velocity-time graph of a particle in one-dimensional motion is shown in
What is the average speed
and (b) ?

Fig. 3.29
Which of the following formulae are correct for describing the motion of the particle
over the time-interval t,
(a) x(t,) = xcſt,) + v ſt,) (t.-t,) f(19 a (t.-t,)
(b) v(t) = v(t,) + a(tz-t,
(c) u = (xſt.) - xeſt,))/(t2-t)
(d) a = (ult.) - vſt,))/(t2-t,
(e) x(t) = x(t,) +
(1) x(t) - x(t)) = area under the u-t curve bounded by the t-axis and the dotted line
shown.
pls solve it​

Answer 1

Answer:

Hello mate ✌️

Explanation:

The correct formulae describing the motion of the particle are (c), (d) and, (f)

The given graph has a non-uniform slope. Hence, the formulae given in (a), (b), and (e) cannot describe the motion of the particle. Only relations given in (c), (d), and (f) are correct equations of motion.
