Question

HELP A car traveling at 4m/s accelerates at a rate of .80m/s2 for 1.8s. What is its final velocity?

Answer 1

Answer:

148(m/s)

Explanation:

V_final = V_current + (acceleration) x (time)

            = 4 + 80 x 1.8 = 148 (m/s)

Answer 2

ANSWER:
Given:
u(initial velocity)=4m/s
a(acceleration)=80m/s^2
t(time)=1.8seconds
To find final velocity denoted by v-
We will use first derivation of motion.
v=u+at
v=4+(80)(1.8)
v=4+144
v=148m/s^-1 or 144m/s
