The acceleration of the jet is
Explanation:
Since the motion of the jet is a uniformly accelerated motion, we can use the following suvat equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
s is the displacement
For the jet in this problem, we have
u = 0
v = 75 m/s
s = 100 m
Solving for a, we find the 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.
