A)At 5.5sec car is at rest because the distance is same as at 5.0sec .

B) At t= 2sec where the distance covered by a car is 20m.

The speed of the car is 10m/s

C) Average speed

4/Savg= 0.14+6.4+5.8+5p.27

Savg = 0.227 m/s

What is non uniform motion ?

When the object is moving with unequal distance along with unequal time intervals.

A cylindrical blood vessel is partially blocked by the buildup of plaque. At one point, the plaque decreases the diameter of the

densk [106]

Answer:10.4 times of initial velocity

Explanation:

Given

Diameter reduced by 69 %

it approaches with velocity $v_0$

suppose its velocity is v during blocked passage

suppose d is the initial diameter and $d_2$ diameter is

$d_2=d(1-0.69)$

$d_2=0.31 d$

$A_2=\frac{\pi d_2^2}{4}$

As flow is constant

$Q_1=Q_2$

$d^2v_0=d_2^2v$

$v=10.40 v_0$

You are pushing a wooden crate across the floor at constant speed. You decide to turn the crate on end, reducing by half the sur

borishaifa [10]

Answer:

D. Half as great

Explanation:

Since we know that the friction force between the surface of crate and ground is given as

$F_f = \mu F_n$

so here we know that

$\mu$ = friction coefficient between two surfaces which depends on the effective contact area between two surfaces

$F_n$ = normal force due to the object

So when we turn the object on another side such that the surface area is half then the friction coefficient will become also half

So here the friction force will also reduce to half

so correct answer will be

D. Half as great

a 60 kg woman in a elevator is accelerating upward at a rate of 1.2 m/s2. What is the gravitational force acting upon the woman?

Flura [38]

The gravitational force acting upon the woman is equal to <u>-588.6N</u>

Why?

To solve the problem, we need to consider that two forces are acting upon the woman, the first one is related to her weight and the second one is related to the acceleration of the elevator.

Gravitational force acting upon the woman:

$Force=m*gravityacceleration\\\\Force=60kg*-9.81\frac{m}{s^{2}}=-588.6N$

Hence, we have that the gravitational force acting upon the woman is equal to -588.6N.

Have a nice day!
