QUESTION
Find velocity when displacement is
20
m
20 \text{ m}
20
m
and time is
4
s
4 \text{ s}
4
s
.
QUESTION
Calculate the time for displacement
Δ
x
=
50
m
\Delta x = 50 \text{ m}
Δ
x
=
50
m
with
v
=
10
m/s
v = 10 \text{ m/s}
v
=
10
m/s
.
QUESTION
What is the initial velocity if
v
=
20
m/s
v = 20 \text{ m/s}
v
=
20
m/s
,
a
=
2
m/s
2
a = 2 \text{ m/s}^2
a
=
2
m/s
2
,
t
=
5
s
t = 5 \text{ s}
t
=
5
s

ANSWER
v
i
=
10
m/s
v_i = 10 \text{ m/s}
v
i
=
10
m/s
. Using
v
=
v
i
+
a
t
v = v_i + at
v
=
v
i
+
a
t
and solving for
v
i
v_i
v
i
.
