Answer:

Strength of materials, Engineering discipline concerned with the ability of a material to resist mechanical forces when in use. A material’s strength in a given application depends on many factors, including its resistance to deformation and cracking, and it often depends on the shape of the member being designed. See also fracture, impact test, materials science, tensile strength, testing machine.

A 0.415-kg mass suspended from a spring undergoes simpleharmonic oscillations with a period of 1.4 s. How much mass, inkilograms

koban [17]

Answer:

m=0.893kg

Explanation:

time period of oscillations is given by= 2π√(m/k)

m: mass of the object

k: spring constant

when T=1.5 and m=0.415

1.5= 2π√(0.415/k)

k= 7.27 N/m

when T= 2.2s

2.2= 2π√(m/7.27)

m=0.893kg

A ball is thrown horizontally at a speed of 16 m/s from the top of a cliff. If the ball hits the ground 6.0 s later, approximate

lina2011 [118]

Answer:

Y = 176.4 m

Explanation:

For the height of cliff we will analyze the vertical motion. We will apply the 2nd equation of motion:

Y = V₀y*t + (0.5)gt²

where,

Y = Height = ?

V₀y = Initial Vertical Velocity = 0 m/s (since, ball is thrown horizontally)

t = time = 6 s

g = 9.8 m/s²

Therefore,

Y = (0 m/s)(6 s) + (0.5)(9.8 m/s²)(6 s)²

Y = 176.4 m

Draw a winding path that covers a distance of 70 miles and finishes with a displacement 20 miles soulthwest of the starting poin

EleoNora [17]

Distance is indeed a scalar amount that also refers to "how the ground an object has encased", and the Displacement is a vector thing that leads "to the extent to which an object is located", and the further calculation can be defined as follows:

Given:

distance= 70 miles

displacement = 20 miles

Displacement formula: $\bold{Velocity = \frac{displacement}{time}}$

Distance formula: $\bold{Distance = speed \times time}$

Suppose you exert 150 n on your refrigerator and push it across the kitchen floor at constant velocity. what friction force acts

Pachacha [2.7K]

Due that the velocity is constant that means that friction force is equal to the force exert by you, otherwise the refrigerator will accelerate or decelerate and in both cases velocity will not be constant.
So then the friction force between refrigerator and floor is 150 Newtons.
