Explanation:

An object which moves 10 km in 30 minutes .

we have to find the average speed of the object .

Changing unit of time into hour

Time = 30/60 hour

Time = 1/2 hour

Time = 0.5 hour

Now let's calculate the average speed

Put the value we get

So, the average speed is 20km/hr

Changing unit of time into hour

Time = 30/60 hour

Now let's calculate the average speed

$\rm\bf \: Average \: speed \: = \frac{Total \: distance}{Total \: time \: }$

Put the value we get

$\dashrightarrow \sf \: Average \: speed \: = \frac{10}{0.5} \\ \\ \dashrightarrow \sf \: Average \: speed \: = \frac{100}{5} \\ \\ \dashrightarrow \sf \: Average \: speed \: = \cancel \frac{100}{5} \\ \\ \dashrightarrow \sf \: Average \: speed \: =20km {hr}^{ - 1}$

So, the average speed is 20km/hr

During the first 4 seconds, its average speed is (100/4) = 25 m/s .

During the full 5 seconds, its average speed is (100/5) = 20 m/s .

The measurement of how fast an object moves over a certain amount of time. question 1 options: speed acceleration displacement velocity which of the following depends on an object s displacement not distance from the starting point? question 2 options: acceleration displacement speed velocity what is the average speed of an object that travels 50 miles in 2 hours? question 3 options: 25 mph 50 mph 100 mph 2 mph which of the following is an example of velocity? question 4 options: 100 mph 25 east 50 mph east 100 miles east which of the following

Step-by-step answer

1. Speed, since we know that $s=\frac{d}{t}$ , where s is speed, d is distance and t is time

2. Velocity, for velocity you need to consider the direction and displacement gives the direction of travel.

3. 25 mph, because $s=\frac{d}{t} =\frac{50}{2} =25mph$

4. 50 mph east, velocity unlike speed has direction.

5.Velocity, displacement gives the formula $v=\frac{d}{t}$ direction.

6. 0, the displacement is zero so velocity is zero

7. It decreases, speed is inversely proportional to time

17. A distance-time graph indicates that an object moves 120 meters in 5 seconds and then remains at rest for 5 seconds. What is the average speed of the object?

Step-by-step answer

P Answered by PhD

12 m/s

Explanation:

Speed is distance moved per unit time and expressed as

S=d/t

S is speed, d is distance and t is time.

When at rest for five minutes, distance moved is zero hence speed is 0/5=0 m/s

When having moved 120 m for 5 s then speed is

S=120/5=24 m/s

Average speed is the average of these two speeda

Average speed=(24+0)÷2=24/2=12 m/s

Therefore, average speed is 12 m/s

A distance time graph indicates a car moves 200 m in 8 s then remains at the rest for 2s what is the average speed of the object (hint: use the formula to calculate speed, add all vectors (8s + 2s) ANF answer using units m/s) please I really need help :(

Step-by-step answer

20 m/s

Explanation:

Average speed = distance / time

v = 200 m / (8 s + 2 s)

v = 20 m/s

Physics

Adistance- time graph indicates that an object moves 100 m in 4 s and then remains at rest for 6s what is the average speed of the object

Step-by-step answer
