Answer:
Explanation:
Impulse is defined as the rate of change of momentum. This is expressed as
Ft = mv - mu = m(v - u)
where
m is the mass of the airplane
F is the force
t is the time in which the force acts
Ft = impulse
v is the final velocity
u is the initial velocity
From the information given,
F = 10
t = 0.6
m = 0,3
u = 0 because it is flying from rest
By substituting these values into the formula,
10 x 0.6 = 0.3(v - 0)
0.3v = 6
v = 6/0.3
v = 20
the airplane's final velocity is 20 m/s
