Answer:
2.23 m/s²
Explanation:
mass of sail boat, m = 20600 kg
Force along east, F1 = 17700 N
Force along north west, F2 = 60000 N
write the forces in vector form
Net force acting on the boat
The magnitude of net force is given by
F = 45922 N
Acceleration = force / mass
a = 45922 / 20600
a = 2.23 m/s²

If two sources emit waves with the same wavelength and a constant phase difference ϕ, they are said to be coherent.
<h3>What is coherent source ?</h3>
- If the frequency and waveform of two wave sources are the same, they are coherent. Waves' optimal quality of coherence makes stationary interference possible.
- When the phase difference between two beams of light is constant, they are coherent; if the phase difference is random or changes, they are noncoherent.
- The concept of a superpositioning at the core of quantum physics and quantum computing is referred to as "quantum coherence." Quantum coherence specifically considers a scenario in which a wave property of an item is split in two and the two waves coherently interfere with one another.
- The interference visibility, which examines the size of the interference fringes in relation to the input waves, is an easy way to measure the degree of coherence; correlation functions provide a precise mathematical definition of the degree of coherence.

Hi there!
We can calculate linear momentum using the following:
p = linear momentum (kgm/s)
m = mass (kg)
v = velocity (m/s)
Calculate:
Now, we can relate force, time, and momentum with the following:
I = Impulse (kgm/s)
F = Force (N)
t = time (s)
Rearrange to solve for force:
The impulse is equal to the change in momentum. Since the car comes to a halt, all of its momentum is lost, so:
Solve:
**Negative force since the positive direction is towards the wall, and the negative direction is away from the wall.
