Asked by Ana

The initial velocity, the final velocity, and the time are given. Using one of the equations of kinematics, you can calculate the displacement directly.

An airplane starts from rest and reaches a takeoff velocity of 60.0 m/s due north in 4.0 s. How far has it traveled before takeoff?

A. 60 m, due north
B. 30 m, due north
C. 240 m, due north
D. 360 m, due north
E. 120 m, due north

The answer is E

Using the equation d= v1*t+1/2at^2
Answered by Henry
V2 = V1 + a*t.
60 = 0 + a*4, a = 15 m/s^2.

d = V1*t + 0.5a*t^2.
V1 = 0, t = 4 s., a = 15 m/s^2, d = ?.
