Answer:
linear acceleration
angular acceleration
Explanation:
As we know that the force due to tension force is upwards while weight of the disc is downwards
so we will have
also we have
now we have
now we have
so we have
linear acceleration
angular acceleration
Explanation:
The given data is as follows.
Mass of the ornament () = 0.9 kg
Length of the wire (l) = 1.5 m
Mass of missile () = 0.4 kg
Initial speed of missile () = 12 m/s
r = 1.5 m
According to the law of conservation of momentum,
Putting the given values into the above formula as follows.
0 + 4.8 = 1.3v
v = 3.69 m/s
Now, the centrifugal force produced is calculated as follows.
=
= 11.80 N
Hence, tension in the wire is calculated as follows.
T =
=
= 24.54 N
Thus, we can conclude that tension in the wire immediately after the collision is 24.54 N.
