Answer:

Explanation:
Initial amplitude=
We are given that
Amplitude after 2 s=A=
We have to find the amplitude after 1 s.
We know that amplitude at any time t

Using the formula






When t=1 s

Use Scoratic it works with any time of subject
Answer:
I would say contact forces
Explanation:
This questions is kind of missing some info but I do know that contact forces need to be either pushed or pulled for a force to happen.
Hope this helped
Power = (work done) / (time to do the work)
Work done = (force to lift the object) x (distance lifted)
In this question, the force is the (weight of the basket)+(your weight).
Work done = (weight of basket+you) x (3 meters)
Time to do the work = 6 seconds.
Power = (weights x 3 meters) / (6 seconds)
<em>Power = (1/2)·(weight of the basket+you, in Newtons) watts</em>
