Question: Initially, the car travels along a straight road with a speed of 35 m/s. If the brakes are applied and the speed of the car is reduced to 13 m/s in 17 s, determine the constant deceleration of the car.

Answer:

1.29 m/s²

Explanation:

From the question,

a = (v-u)/t............................ Equation 1

Where a = deceleration of the car, v = final velocity of the car, u = initial velocity of the car, t = time.

Given: v = 13 m/s, u = 35 m/s, t = 17 s.

a = (13-35)/17

a = -22/17

a = -1.29 m/s²

Hence the deceleration of the car is 1.29 m/s²

Define the term pressure

ohaa [14]

Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. ... In SI units, pressure is measured in pascals; one pascal equals one newton per square metre. Atmospheric pressure is close to 100,000 pascals.

A hot air balloon is descending with a velocity of 2.0 m/s straight down. At a height of 6m, a champagne bottle is opened to cel

lapo4ka [179]

Answer:

a

$v = 5.39 \ m/s$

b

Horizontal component

$v_x = 5.00 \ m/s$

vertical component

$v_y = - 2.0 \ m/s$

c

$t = 0.921 \ s$

d

$d = 4.605 \ m$

Explanation:

Generally from the question we can deduce that he initial velocity of the cork, as seen by an observer on the ground in terms of the x unit vector is

$v_x = 5.00 \ m/s$ due to the fact that the cork is moving horizontally

Generally from the question we can deduce that the vertical and horizontal components of the initial velocity is

$v_y = - 2.0 \ m/s$ due to the fact that the balloon is moving downward which is the negative which will also cause the cork to move vertically with the balloon speed

Generally the initial velocity (magnitude and direction) of the cork, as seen by an observer on the ground is mathematically represented as

$v = \sqrt{ v^2 _x + v^2 _y }$

$v = \sqrt{ 5^2 + (-2)^2 _y }$

$v = 5.39 \ m/s$

Generally the initial direction of motion as seen by the same observer is mathematically represented as

$\theta = tan^{-1}[\frac{2}{5} ]$

$\theta = 21.80^o$

Generally the time taken by the cork in the air before landing is mathematically represented as

$D = ut + \frac{1}{2} g t^2$

So D = 6 \ m from the question

g = 9.8 \ m/s^2

u = $v_y$ = 2 m/s this because we are considering the vertical motion

So

$6 = 2 t + \frac{1}{2} * 9.8* t^2$

$6 = 2 t + 4.9 t^2$

Solving using quadratic formula w have that

$t = 0.921 \ s$

Generally the distance of the cork from the balloon is mathematically represented as

$d = v_x * t$

$d = 5 * 0.921$

$d = 4.605 \ m$

You have just landed your first job as a structural engineer and you have been asked to design a regional airport for small plan

lidiya [134]

Answer: $197.40\ m$

Explanation:

Given

final velocity at takeoff $v=28.1\ m/s$

Acceleration of the plane can be $a=2\ m/s^2$

Initial velocity is zero for the plane i.e. $u=0$

Using the equation of motion

$\Rightarrow v^2-u^2=2as\quad [\text{s=displacement}]\\\text{Insert the values}\\\Rightarrow (28.1)^2-0=2\times 2\times s\\\\\Rightarrow s=\dfrac{789.61}{4}\\\\\Rightarrow s=197.40\ m$

Thu,s the minimum length must be $197.40\ m$
