Answer:
D a conclusion
Explanation:
The definition of hypothesis is a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation
The restoring force in a simple harmonic oscillator acts as a restoring force, acting opposite in direction of and proportional in magnitude to the displacement. This has the result that when the oscillator reaches the equilibrium point, it has gained its maximum kinetic energy (and therefore velocity) while the magnitude of the restoring force, and therefore the acceleration, is 0.
Choice A
Answer:
33 kg m/s
Explanation:
The momentum of an object is given by:

where
m is the mass of the object
v is the velocity of the object
In this problem, the total mass of the child and the wagon is m =22 kg, while the velocity is v = 1.5 m/s, therefore the momentum is
