To find the top speed of the fastest helicopter, the Westland Lynx, we need to use the concept of momentum and relate it to speed.
The momentum (p) of an object is defined as the product of its mass (m) and its velocity (v):
p = m * v
Rearranging this equation, we can solve for the velocity (v):
v = p / m
Given that the mass of the Westland Lynx is 3.343 x 10^3 kg and its maximum momentum is 3.723 x 10^5 kg.m/s, we can substitute these values into the equation to find the top speed:
v = (3.723 x 10^5 kg.m/s) / (3.343 x 10^3 kg)
Calculating this, we get:
v = 111.3 m/s
Therefore, the top speed of the Westland Lynx helicopter is approximately 111.3 m/s.
