How Far East have you traveled if you ran 80 meters northeast

Physics
1 answer:
CaHeK987 [17]3 years ago
6 0

Explanation:

Given parameters:

Displacement = 80m

Unknown:

Displacement eastward = ?

Solution:

Displacement is the distance traveled in a specific direction.

To find the distance traveled eastward, we need to find the horizontal component of his displacement using the cosine rule:

   Cos Ф = \frac{adjacent }{hypotenuse}

The unknown is the adjacent;

 Adjacent = hypotenuse CosФ = 80 cos 45 = 56.57m

His displacement is 56.57m due east

How long should a spring be stretched for it to store 45 J of energy? The force constant of the spring is
ELEN [110]

Answer:

x = 0.4 m

Explanation:

When a spring is stretched from its equilibrium position. Some energy is stored in the spring. This energy is called the elastic potential energy of the spring. The formula used to calculate the magnitude of this stored energy is given as follows:

P.E = (1/2)kx²

where,

P.E = Elastic Potential Energy Stored in the spring = 45 J

k = Spring Constant = 540 N/m

x = amount of stretching = ?

Therefore,

45 J = (1/2)(540 N/m)x²

x² = (45 J)(2)/(540 N/m)

x = √(0.167 m²)

<u>x = 0.4 m</u>

Reading Check: (Describe) how pressure changes as the velocity of a fluid<br> increases.
juin [17]

Answer:

Bernoulli's equation states mathematically that if a fluid is flowing through a tube and the tube diameter decreases, then the velocity of the fluid increases, the pressure decreases, and the mass flow (and therefore volumetric flow) remains constant so long as the air density is constan
