What? Can you take a picture of the question please?
Solution :
Velocity of cart at t = 0 s is, u = 1.8 m/s .
Distance covered in 3 seconds is :
d = 1.8 m/s × 3 s
d = 5.4 m.
So, position of cart after t = 3 seconds is x = 2.8 + 5.4 m = 8.2 m .
Hence, this is the required solution.
Answer:
It takes you 32.27 seconds to travel 121 m using the speed ramp
Explanation:
<em>Lets explain how to solve the problem</em>
- The speed ramp has a length of 121 m and is moving at a speed of
2.2 m/s relative to the ground
- That means the speed of the ramp is 2.2 m/s
- You can cover the same distance in 78 seconds when walking on
the ground
<em>Lets find your speed on the ground</em>
Speed = Distance ÷ Time
The distance is 121 meters
The time is 78 seconds
Your speed on the ground = 121 ÷ 78 = 1.55 m/s
If you walk at the same rate with respect to the speed ramp that
you walk on the ground
That means you walk with speed 1.55 m/s and the ramp moves by
speed 2.2 m/s
So your speed using the ramp = 2.2 + 1.55 = 3.75 m/s
Now we want to find the time you will take to travel 121 meters using
the speed ramp
Time = Distance ÷ speed
Distance = 121 meters
Speed 3.75 m/s
Time = 121 ÷ 3.75 = 32.27 seconds
It takes you 32.27 seconds to travel 121 m using the speed ramp
Depending on what way you are trying to use it electrons connect to almost anything just like little balls of magnetics think of it that way. of it being able to just force and charge into any thing.
