Answer:
The bin moves 0.87 m before it stops.
Explanation:
If we analyze the situation and apply the law of conservation of energy to this case, we get:
Energy Dissipated through Friction = Change in Kinetic Energy of Bin (Loss)
F d = (0.5)(m)(Vi² - Vf²)
where,
F = Frictional Force = μR
but, R = Normal Reaction = Weight of Bin = mg
Therefore, F = μmg
Hence, the equation becomes:
μmg d = (0.5)(m)(Vi² - Vf²)
μg d = (0.5)(Vi² - Vf²)
d = (0.5)(Vi² - Vf²)/μg
where,
Vf = Final Velocity = 0 m/s (Since, bin finally stops)
Vi = Initial Velocity = 1.6 m/s
μ = coefficient of kinetic friction = 0.15
g = 9.8 m/s²
d = distance moved by bin before coming to stop = ?
Therefore,
d = (0.5)[(1.6 m/s)² - (0 m/s)²]/(0.15)(9.8 m/s²)
<u>d = 0.87 m</u>

Hint: Here, we can see that 12 and 13 are consecutive numbers. So, all numbers between squares of 12 and 13 are non-square numbers. Therefore, first find squares of 12 and 13 and then subtract square of 12 from square of 13, we get numbers of non-square numbers. At the last subtract 1 from the result obtained as both extremes numbers are not included.
Complete step-by-step answer:
In these types of questions, a simple concept of numbers should be known that is between squares of two consecutive numbers all numbers are non-square numbers. Also one tricky point should remember that whenever we find the difference between two numbers we get a number of numbers between them including anyone of the extreme numbers. So we subtract 1 to exclude both extreme numbers.
Square of 12 = 122=144 and square of 12 = 132=169
As 12 and 13 are consecutive numbers so all numbers between their squares will be non-square numbers.
Therefore, 169 – 144 = 25
Total number of numbers between 169 and 144 (i.e., excluding 144 and 169) = 25 – 1 = 24.

Answer
given,
mass of the ball = 3 kg
swing in vertical circle with radius = 2 m
work done by the gravity = ?
work done by the tension = ?
Work done by the gravity = - m g Δh
Δ h = 2 + 2 = 4 m
Work done by the gravity =
= -117.6 J
work done by gravity is equal to -117.6 J
Work done by tension will be equal to zero.
Zero because tension is always perpendicular to velocity
work done by tension is equal to 0 J
