Question

answer question below

Answer 1

Answer:

option c

( - 4/15 ms^-2)

Explanation:

From the graph -

• initial velocity = 4 ms^-1
• final velocity = 0 ms^-1
• time = 15 s

Formula :-

$v - u = at$

• v = final velocity
• u = initial velocity
• a = acceleration
• t = time

$= > 0 - 4 = a \times 15$

$= > - 4 = a \times 15$

$= > a = - \frac{4}{15}$

Declaration (negetive of acceleration) = ( -4/15 ms^-2)
