Question

Which diagram shows the effect of cutting the
acceleration in Part A in half and not changing
the value of the initial velocity?

Answer 1

Acceleration is the rate of change of velocity over time. The diagram that shows the effect of cutting acceleration by half without changing initial velocity is graph (c)

The equation is given as:

$v = 2t + 4$

The first equation of motion is:

$v = u + at$

By comparing both equations, we have:

$u = 4$ --- initial velocity

$a = 2$ --- acceleration

When the acceleration is cut in half, the new acceleration is:

$a_{new} = \frac a2$

$a_{new} = \frac 22$

$a_{new} = 1$

So, the equation of velocity is:

$v = u + at$

$v = 4 + 1 \times t$

$v = 4 + t$

When $t = 0$

$v = 4 + 0 = 4$

When $t = 1$

$v = 4 + 1 = 5$

The graph of velocity that satisfies $v = 4 + t$ and the values of time (t) and velocity (v) tested above is (c).
