A biker accelerates from Om/s to 8m/s ub 3 seconds. What is his acceleration? Isthis acceleration higher than that of a car wihich accelerates from 0 to 30m/s in
8 seconds
Answers
Answer:
The acceleration of the biker is 2.67m/s² while that of the car is 3.75m/s². So, the acceleration of the biker is NOT HIGHER than that of the car.
Explanation:
Given that,
acceleration of biker A= ?
Initial velocity of biker Vi = Om/s
Final velocity of biker Vf = 8m/s
Time taken (t) = 3 seconds
Since acceleration is the rate of change of velocity per unit time
i.e Acceleration = (Vf - Vi) / t
A = (8m/s - 0m/s) / 3s
A = 2.67 m/s²
To know which is higher, calculate the acceleration of the car
acceleration of car A= ?
Initial velocity of car Vi = Om/s
Final velocity of car Vf = 30m/s
Time taken (t) = 8 seconds
Acceleration = (30m/s - 0m/s) / 8s
A = 30m/s / 8s
A = 3.75 m/s²
Since, the acceleration of the biker is 2.67m/s² while that of the car is 3.75m/s², the acceleration of the biker is NOT HIGHER than that of the car.

Answer: there would be no motion
Explanation:
There would be no motion,as the object get stuck
Answer:
Friction is a force that opposes motion between any surfaces that are touching. Friction can work for or against us. For example, putting sand on an icy sidewalk increases friction so you are less likely to slip. On the other hand, too much friction between moving parts in a car engine can cause the parts to wear out.

Thewave speed will be 210 m/sec. The wave speed is found as the product of the wavelength and frequency of the wave.
What is wavelength?
The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The relationship between the wave's wavelength, time, and speed is given as;
Wavelength = speed of wave / time period
Hence, the wave speed will be 210 m/sec.

I always thought that 'polygamy' refers to the social system in which a man
may have more than one wife, and I thought there's some other word for
where a woman is married to more than one man.
But when I went to look it up just now to answer your question, (which by the
way you could also have done very easily), I found a definition that says it's a
"state of marriage between many spouses". That doesn't specify genders, so
I guess it means any marriage that involves more than two people, no matter
how the genders may be represented or distributed within it.
what is serap's momentum
what is the total momentum of the entire system?
Answers
1) David's momentum is 12,000 kg m/s east
2) Serap's momentum is 15,000 kg m/s east
3) The total momentum is 27,000 kg m/s east
Explanation:
1)
The momentum of an object is given by
where
m is the mass of the object
v is its velocity
In this problem, we have:
m = 600 kg is the mass of David+his dune buggy
is their velocity (taking east as positive direction)
Therefore, David's momentum is:
And the direction is the same as the velocity (east).
2)
Again, we can use the same equation:
where this time
m is the mass of Serap+dunebuggy
v is their velocity
In this problem,
m = 500 kg is the mass of Serap + dunebuggy
v = 30 m/s is their velocity (positive since it is also in the east direction)
Substituting, we find
And the direction is the same as the velocity (east).
3)
The total momentum of the entire system is given by
where
is David's momentum
is Serap's momentum
In this problem, we have the following data, found in the previous parts:
The two momentum have same direction (east), so we can simply add them together to find the total momentum:
And the direction is still East.
