Answer:
(A) Force on the object will be 58.85 N
(B) Apparent weight will be equal to 57.21 N
Explanation:
We have given mass of Neptune m = 1026 kg
Radius R = 25000 Km
Time period = 16 hour
We know that 1 hour = 3600 sec
So 16 hour = 16×86400 = 57600 sec
Acceleration due to gravity at north pole of Neptune
(A) Mass of the object m = 5.5 kg
So gravitational force on the object
(B) Velocity will be equal to
Apparent weight of the object will be equal to
Answer:
-14 m/s
Explanation:
Saki's initial velocity is:
where we put a negative sign because the problem tells us to use a coordinte system in which rightward is positive, while Saki's initial velocity is towards the left.
Saki's acceleration due to the breeze is:
Where again, we put a negative sign since the acceleration is leftward.
In order to find Saki's velocity after t = 6 s, we can use the following equation:
And substituting all the numbers, we get
and the negative sign means the new velocity is leftwards.
