Venus spins the opposite direction.
Answer:
5m/s2
Explanation:
Data obtained from the question include:
m (mass) = 2000 kg
F (force) = 10000N
a (acceleration) =?
Using the formula F = ma, the acceleration of the truck can be obtained as follow:
F = ma
a = F/m
a = 10000/2000
a = 5m/s2
The acceleration of the truck is 5m/s2
Answer:
b)7.89 g
c) 7.91 g
d) 7.97 g
Explanation:
The accepted value for the measurement is 7.92 g, while the precision of the instrument is 0.05 g. Therefore, the interval of the accepted values will be the central value plus and minus the precision, so:
- Minimum accepted value: 7.92 g - 0.05 g = 7.87 g
- Maximum accepted value: 7.92 g + 0.05 g = 7.97 g
So, the accepted interval is
7.87 g - 7.97 g
Therefore, all the values that lie within this interval are accepted. So the accepted values are:
b)7.89 g
c) 7.91 g
d) 7.97 g
You can easily tell by shaking the envelope by making the sheets inside it overlap then flip it around then start feeling then you can feel 4 sheets
So, <u>the acceleration of the car is -1</u><u>.</u><u>25 m/s²</u>. In other word, the car is also decelerating by 1.25 m/s².
<h2>Introduction</h2>
Hi ! I will help you to discuss about "deceleration in a straight line movement". Please note in advance that deceleration is acceleration which has a negative value. <u>When an object decelerates, the object will continue to move until it reaches a certain speed (which is less than before) or until it stops</u>. The higher the deceleration value, an object that is moving will stop faster and cover a shorter distance.
<h3>Formula Used</h3>
In this opportunity, I will give you the following equation to express the relationship between final velocity and initial velocity, acceleration, and distance.
With the following condition:
- = final velocity of an object (m/s)
- = initial velocity of an object (m/s)
- a = acceleration that happen (m/s²)
- s = the shift or distance of the object (m)
<h3>Problem Solving </h3>
We know that:
- = initial velocity of an object = 72 km/h = 20 m/s
- = final velocity of an object = 54 km/h = 15 m/s
- s = the shift or distance of the object = 70 m
Note :
- 1 m/s = 3.6 km/h. So 10 m/s = 36 km/h
What was asked ?
- a = acceleration that happen = ... m/s²
Step by step :
<h3>Conclusion </h3>
Here, we see that the acceleration is -1.25 m/s². In other words, the car is also decelerating by 1.25 m/s².
