2800 m

<h3>Further explanation</h3>

Given

time = 80 s

average velocity = 35 m/s

Required

total distance before it broke down

Solution

Average velocity : total displacement : total time

Can be formulated

avg velocity = Δx : Δt

Input the value :

Δx=avg velocity x Δt

Δx = 35 m/s x 80 s

Δx = 2800 m

In addition, if we are asking for velocity, we must know the starting and ending points (displacement)

But if we calculate the total distance, what is written is the average speed

avg speed = total distance : total time

Answer:

The Laws of Badminton

A match consists of the best of 3 games of 21 points.

Every time there is a serve – there is a point scored.

The side winning a rally adds a point to its score.

At 20 all, the side which gains a 2 point lead first, wins that game.

At 29 all, the side scoring the 30th point, wins that game.

Answer:

1.92 m/s

Explanation:

Velocity is defined as the distance moved per unit time with consideration of the direction. The direction aspect differentiates speed from velocity since for speed, we don't need to consider the direction.

$v=\frac {d}{t}$

Distance moved for circular path is equal to its circumference and the circumference is given by $2\pi r$ where r is the radius and substituting $2\pi r$ for d then

$v=\frac {2\pi r}{t}$

Substituting 5.5 m for r and 18 s for t then

$v=\frac {2\pi \times 5.5}{18}=1.919862177 m/s\approx 1.92 m/s$

To the nearest hundredth, the velocity is 1.92 m/s

Gnoma [55]

Answer:

91.84 m/s²

Explanation:

velocity, v = 600 m/s

acceleration, a = 4 g = 4 x 9.8 = 39.2 m/s^2

Let the radius of the loop is r.

he experiences a centripetal force.

centripetal acceleration,

a = v² / r

39.2 x r = 600 x 600

r = 3600 / 39.2

r = 91.84 m/s²

Thus, the radius of the loop is 91.84 m/s².

Answer:

acceleration = 22.14 m/s²

time = 2.80 s

Explanation:

given data

initial velocity = 31.0

final velocity =

time = 1.40

solution

we get here acceleration that is

acceleration = $\frac{v(final) - v(initial)}{t}$ ...............1

acceleration = $\frac{31-0}{1.40}$

acceleration = 22.14 m/s²

and

by kinematic equation of motion

v = u +at .........2

t = $\frac{62-0}{22.14}$

time = 2.80 s
