Answer:
54.55 m/s
Explanation:
From the question above,
Change in velocity = impulse/mass
Δv = I/m = Ft/m................... Equation 1
Where F = force, t = time, m = mass
Given: F = 20 N, t = 30 s, m = 11 kg
Substitute these values into equation 1
Δv = (20×30)/11
Δv = 600/11
Δv = 54.55 m/s
Hence the change in velocity of the body is 54.55 m/s

Answer:
second law
Explanation:
Newton's second law explains how much motion a force creates.
Here in order to find out the distance between two planes after 3 hours can be calculated by the concept of relative velocity
here
speed of first plane is 700 mi/h at 31.3 degree
speed of second plane is 570 mi/h at 134 degree
now the relative velocity is given as
now the distance between them is given as
so the magnitude of the distance is given as
miles
so the distance between them is 2985.6 miles
