Question

Q).From the following graph, find the sign of
1).velocity
2).acceleration
give reasons for each answer.

Answer 1

Answer:

this graph is wrong since here time is given negative which is not possible.

Answer 2

Answer:

v = negative

a = negative

Explanation:

Since displacement is negative,

And, v = dx/dt

v is negative

Since velocity is negative,

And, a = dv/dt

a is negative
