A body accelerate uniformly from rest at the rate of 3meters per seconds for 8 sec . calculate the distance covered by the body
pishuonlain [190]

Answer:

96 m

Explanation:

Given:

v₀ = 0 m/s

a = 3 m/s²

t = 8 s

Find: Δx

Δx = v₀ t + ½ at²

Δx = (0 m/s) (8 s) + ½ (3 m/s²) (8 s)²

Δx = 96 m

Bone has a Young's modulus of about
Oksanka [162]

Answer:

505.62 mm

Explanation:

Young's modulus of a material is given by,

Y=\frac{Stress}{Strain}

Stress is the force experienced by the material per unit area (which is why stress has the same units as pressure).

Strain is the ratio between the change in length/area/volume to the original length/area/volume of the material (and hence a dimensionless quantity). Basically, it gives us a measure of the change in dimensions due to the stress experienced.

So, for the given problem,

Y=\frac{Stress}{\Delta L/L}

or, 1.8\times100=\frac{1.59\times108}{\Delta L/0.53}      (since we need to find the compression of the bone at the critical stress point)

or, \Delta L=\frac{1.59\times108\times0.53}{1.8\times100} m=0.50562m=505.62mm

How does torque of rotating body relate to velocity
Fudgin [204]

Answer:

We know that the torque can be calculated as follows:

T = rpsinα

With r being the distance of the body from the center of the circumference he has as trajectory, p being the momentum of the body and sinα being the sine of the angle between the 2 vectors: r and p.

It's pretty obvious that T is directly proportional to the momentum, that can be written as p = m·v, with m being the mass of the object and v the velocity of the object.

Car a is heading north with a velocity of 14 m/s. car b is traveling north also, with a velocity of 19 m/s. what is the relative
kicyunya [14]
a.)  Relative velocity = velocity of car B - velocity of car A
                             = 19 - 14
                             = 5 m/s
Hope this cleared your doubt, feel free to ask any question regarding this and have a nice day ahead! :)
