Question

During takeoff, an airplane goes from 0 to 60 m/s in 10 s.
(b) How fast is it going after 3 s?
c) How far has it traveled by the time it reaches 60 m/s?

PLEASE HELP!!

Answer 1

Answer:

see below

Explanation:

acceleration = Δv /Δt

  for this situation  60 / 10 = 6 m/s^2

B)  vf = vo + at

vf = 0   + 6(3)  = 18 m/s   after 3 seconds

C)   vf = at

60 = 6 ( t)      t = 10 seconds   ( actually, this was given)  

d = 1/2 a t^2

  = 1/2 (6) (10)^2 = 300 m
