3 0

Answer:

These are called kinematics equations.

Explanation:

These equations are used when there is either a constant velocity motion or a constant acceleration motion.

For questions A, B, C, and D. Determine if the Kinetic Energy will increase, decrease or stay the same based on the directions o
yuradex [85]

Explanation:

KE = 1/2*m*v^2

mass won't change

but velocity is

A: the force is pushing against the direction of the object, so velocity is decreasing, so KE is decreasing

B: the F net line is pretty much straight up, which means there is no net force pushing to the left, but velocity is still increasing

Why? Because if you use the pythagorean theorem, the hypotenuse is always longer than the legs.

Note: velocity only ever stays the same if there is no net force (or 0 acceleration), so all four of these are either decreasing or increasing

C: there is a net force to the right, so velocity is increasing

D: There is a net force to the right but velocity is to the left, so velocity is decreasing

Hope I got these right

Q|C A string with linear density 0.500 g/m is held under tension 20.0 N. As a transverse sinusoidal wave propagates on the strin
julia-pushkina [17]

A string with linear density 0.500 g/m.

Tension 20.0 N.

The maximum speed  v_{y, max}

The energy contained in a section of string 3.00 m long as a function of v_{y, max}.

We are given following data for string with linear density held under tension :

μ = 0.5 \frac{g}{m}

  = 0.5 x 10⁻³ \frac{kg}{m}

T = 20 N

If string is L = 3m long, total energy as a function of v_{y, max} is given by:

E = 1/2 x μ x L x ω² x A²

  = 1/2 x μ x L x v^{2} _{y, max}

  = 7.5 x 10⁻⁴ v^{2} _{y, max}

So, The total energy as a function of  v^{2} _{y, max} = 7.5 x 10⁻⁴ v^{2} _{y, max}

two tugboats pull a disabled supertanker. each tug exerts a constant force of 2.20×106 n , one at an angle 19.0 ∘ west of north,
asambeis [7]

The amount of work the two tugboats completed on the supertanker W = 3.12 × 10^9 joules .

Work is a physics term used to describe the energy transfer that takes place when an object is moved over a distance by an external force, at least some . The component of the force acting along the path multiplied by the length of the path can be used to calculate work if the force is constant. Mathematically, this idea is expressed as W = fd, where W is the work and f is the force multiplied by d, the distance. Work is completed when the force is applied at an angle of with respect to the displacement. Performing work on a body involves moving it in its entirety from one location to another as well as other methods.  However, the work is thought to be negative if the applied force is in opposition to the item's motion, indicating that energy is being pulled away from the object
