QUESTION
If velocity and acceleration have the same sign, what happens to speed?
QUESTION
What does a horizontal line on a velocity-time graph indicate?
QUESTION
Find the acceleration given
v
i
=
5
m/s
v_i = 5 \text{ m/s}
v
i
=
5
m/s
,
v
f
=
15
m/s
v_f = 15 \text{ m/s}
v
f
=
15
m/s
, and
t
=
2
s
t = 2 \text{ s}
t
=
2
s
.

ANSWER
a
=
5
m/s
2
a = 5 \text{ m/s}^2
a
=
5
m/s

. Using
a
=
Δ
v
t
=
10
2
a = \frac{\Delta v}{t} = \frac{10}{2}
a
=
