Question

A car is traveling due west at 20.0 m/s. Find the velocity of the car after 3.00 s if its acceleration is
1.0 m/s2 due east. Assume the acceleration remains constant.
(A) 17.0 m/s west (B) 17.0 m/s east (C) 23.0 m/s west (D) 23.0 m/s east​

Answer 1

Answer:

initial velocity (u)=20.0m/s

time(t)=3s

final velocity(v)=?

a=1.0m/s^2

we know v=u+at

v=20+1×3

v=23m/s east

D)
