It would be Atoms, they’re all made up of these tiny particles
Answer:
Time, t = 10 seconds
Explanation:
Given the following data;
Mass = 10kg
Force = 10N
Final velocity = 10m/s
Initial velocity = 0m/s
To find the time;
First of all, we would find the acceleration of the box.
Force = mass * acceleration
10 = 10 * acceleration
Acceleration = 10/10 = 1m/s²
Now, we can find the time by using the first equation of motion;
V = U + at
10 = 0 + 1t
10 = t
Time, t = 10 seconds
Therefore, it will take 10 seconds for the box to come to a complete stop.
The problem wants to compute how long does it take for the acceleration to occur if a car travelling at 7m/s accelerates uniformally at 2.5 m/s^2 to reach a speed of 12 m/s and base on that, the time duration would be 2 seconds. I hope this would help
It accelerates from rest at 1.1 m/s^2 for 20s.
<span>s = at^2/2 </span>
<span>s = (.5)(1.1)(20)^2= 220m </span>
<span>then it travels 1100m </span>
<span>Then it slows down at 2.2m/s^2 until it stops at the station. </span>
<span>Calculate the train's speed: </span>
<span>v = at </span>
<span>v = (1.1)(20) = 22m/s
</span>
<span>Now, calculate the time to stop: </span>
<span>v = at </span>
<span>t = 22/2.2 = 10s </span>
<span>s = t(u+v)/2 </span>
<span>s = 10(0+22)/2 = 110m </span>
<span>(A) Total distance = 220 +1100+110 = 1430m </span>
<span>(B) Time = 20 + 1100/22 + 10 = 80s</span>
