Answer:
a)V= - 1.11 m/s
b)V= 0.833 m/s
Explanation:
Given that
M (Mass of lumberjack)= 98 kg
Final velocity of lumberjack ,V₁= 3.3 m/s
m (Mass of log) = 290 kg
a)
There is no any external force that is why linear momentum will be conserved
Pi=Pf
initially both are at rest so Pi=0 ( P = m v)
Lets take speed of log is V
0= M V₁ + m V
V = - M V₁ / m
V= - 98 x 3.3 / 290
V= - 1.11 m/s
b)
Now again from linear momentum conservation
(m + M )V =M V₁
V= M V₁(m+M)
By putting the values
V= 98 x 3.3/ (98 + 290 )
V= 0.833 m/s

Answer:
The other angle is 120°.
Explanation:
Given that,
Angle = 60
Speed = 5.0
We need to calculate the range
Using formula of range
...(I)
The range for the other angle is
....(II)
Here, distance and speed are same
On comparing both range
Hence, The other angle is 120°
The answer is B hope this helped you !!
Explanation:
Dasht-e Loot, Iran is the hottest,, and the coldest is the East Antarctic Plateau. The reason that part of Iran is the hottest is because it's near the Arabian deserts, and as you know the deserts can be pretty hot. The coldest part of the Earth is that cold because it doesn't get as much sunlight, the reason for that is because they don't get any direct sunlight.
