Answer

B. Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating.

Explanation

Acceleration is the rate of change of velocity. It is calculated as follows;

a = (v - u)/t

Where a⇒ acceleration

v ⇒ final velocity

u ⇒ initial velocity

t ⇒ time taken.

For Gabriella;

a = (32-55)/10 = -23/10 = -2.3

Since acceleration is negative, Gabriella was desecration (slowing down.

For Franklin,

a = (50-50)/8.5 = 0

This means no acceleration.

For Kendall;

a = (67-53.2)/6 = 13.8/6 = 2.3

Positive acceleration means, he was speeding up.

From the choices the correct answer is B. Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating.

What is the relative energy expense of galloping rather than trotting at 3.5 m/s?

labwork [276]

Answer: Trotting uses only 75 percent of the energy as galloping

Explanation: Trotting is only 300 J/m, whereas galloping is roughly 400 J/m

A solid sphere, solid cylinder, and a hollow pipe all have equal masses and radii and are of uniform density. If the three are r

scZoUnD [109]

Answer:

A ) SOLID SPHERE

Explanation:

Moment of inertia of solid sphere = 2/5 M R²

= M K² , K is called radius of gyration

K = √2/5 R

Moment of inertia of solid cylinder = 1/2 M R²

= M K² , K is called radius of gyration

K = 1 /√2 R

Moment of inertia of solid sphere = M R²

= M K² , K is called radius of gyration

K = R

For rolling on inclined plane , acceleration

a = $\frac{gsin\theta}{1+\frac{K^2}{R^2} }$

Putting the value of K for solid sphere

a for solid sphere

a = g sinθ / ( 1 +2/5)

a = .714 g sinθ

Putting the value of K for solid cylinder

a for solid cylinder

a = g sinθ / ( 1 +1/2)

a = .666 g sinθ

Putting the value of K for hollow pipe

a for hollow pipe

a = g sinθ / ( 1 +1 )

a = . 5 g sinθ

So we see that acceleration a for solid sphere is greatest and a for hollow pipe is the least. Hence solid sphere will reach the bottom earliest and hollow pipe will reach the bottom the latest.
