Answer:
x(t) = -3sin2t
Explanation:
Given that
Spring force of, W = 720 N
Extension of the spring, s = 4 m
Attached mass to the spring, m = 45 kg
Velocity of, v = 6 m/s
The proper calculation is attached via the image below.
Final solution is x(t) = -3.sin2t
Liter
The Basic Unit for Volume
The liter, which is the basic unit of volume, was originally defined as the volume occupied by 1 kilogram of water, but today it's simply one-thousandth of a cubic meter

Answer:
.D)The Vector sum of the linear momenta of the fragments must be zero.
Explanation:
.D)The Vector sum of the linear momenta of the fragments must be zero.
This statement is true. This is so because no external force is acting on the masses. The motion is created by internal force so momentum of fragments will be conserved.
A) this statement is false because kinetic energy was zero in the beginning ( the bomb was stationary in the beginning )
B ) This statement is false because it violates the law of conservation of momentum .( it does not violates only when all the fragments have equal mass )
C ) This statement is zero because kinetic energy is not a vector quantity so two kinetic energy when added can not sum up to zero.
