Seems that the given question is incomplete. Find the attachment of the complete query.
According to the question,
- x₁ = -0.20 m
- x₂ = 0 m
- k = 60 N/m
Now,
⇒ 
⇒ 
⇒ 
By putting the values, we get

The Monera kingdom is different from all of the other kingdoms because it contains organisms that are the most primitive or the most basic living things. The organisms that are in the Monera kingdom are usually classified as bacteria.
Answer:
⇒ 401.6 ± 7.1 ms
⇒ 57.2 ± 1.6 kg
⇒ 8.1 × 107 ± 2.9 × 105 m
⇒ 2.1 ± 8.8 µN
⇒ 294 ± 0.005 cm
Explanation:
As given all equation we do without calculation we will get here round these calculations which is given below as
a) 401.6473 ± 7.0912 ms
⇒ 401.6 ± 7.1 ms
b) 57.212 ± 1.612 kg
⇒ 57.2 ± 1.6 kg
c) 8.12754×107 ± 2.847×105 m
⇒ 8.1 × 107 ± 2.9 × 105 m
d) 2.94 ± 8.803 µN
⇒ 2.1 ± 8.8 µN
e) 294 ± 0.00481 cm
⇒ 294 ± 0.005 cm
Answer:
72 J
Explanation:
Total kinetic energy will be tge sum of rotational and translational energy.
Rotational kinetic energy is given by 
where I is moment of inertia which is given by 
and here m is mass, r is radius. Also, 
hence making \omega the subject then 
where v is the velocity.
Rotational kinetic energy=
This is same as the formula for translational kinetic energy which is given by 
Therefore, total kinetic energy= 
Substituting m with 2 kg and v with 6 m/s then total energy will be
