Velocity of a particle at any time
t
t
t
is
v
=
(
2
i
^
+
2
t
j
^
)
m/s
\mathbf{v} = (2\hat{i} + 2t\hat{j})\text{ m/s}
v
=
(
2

)
m/s
. Find acceleration and displacement of particle at
t
=
1
s
t = 1\text{ s}
t
=
1
s
. Can we apply
v
=
u
+
a
t
\mathbf{v} = \mathbf{u} + \mathbf{a}t
v
=
u
+
a
t
or not?
