what is the direction of the acceleration of the sailboat, expressed as an angle in degrees of north of east

Magnitude of acceleration, a = 1.90 m/s²

Direction of the acceleration, α = N24.9°E

Note: The question is incomplete. The complete question is given below:

A sailboat has a mass of 2160 kg and experiences two horizontal forces. One is due to the action of the water on the hull of the boat and is directed east and has a magnitude of 1990 N. The other is due to the action of the wind on the sails and is directed northeast with a magnitude of 2440 N.

What is the magnitude of the acceleration of the sailboat in m/s2?

What is the direction of the acceleration of the sailboat, expressed as an angle in degrees north of east?

Explanation:

The the vector sum of all the forces constitute the net force acting on the sailboat.

Resolving the forces into horizontal and vertical components:

Horizontal forces:

X = 1990 cos90 +  

2440 cos 45°

X = 1725 N

Vertical forces:

Y = 1990 sin90° + 2440 sin45°

Y = (1990 + 1725) N

Y = 3715 N

Net force,  F = √(X² + Y²)

F = √(1725² + 3715²)

F = 4095.5 N

According to Newton's law, Net force causes acceleration, a, of a body

Net force = mass * acceleration  

a = (Net force)/m

a = 4095.5/2160

a = 1.90 m/s²

Magnitude of acceleration, a = 1.90 m/s²

Direction of the acceleration, α = tan⁻¹ (Y/X)

α = tan⁻¹ (3715/1725)

α = 65.1

Direction of the acceleration, α, North of east = 90 - 65.1°

Direction of the acceleration, α = N24.9°E

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like . (i crazy)

most famous scientist who contributed to this physics are:

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
