Answer:
position as a function of time is y = 0.05 × cos(9.9)t
Explanation:
given data
mass = 5 kg
length = 10 cm = 0.1 m
displaced = 5 cm
to find out
position as a function of time
solution
we will apply here equilibrium that is
mass × g = k × length
put here value and find k
k = 
k = 490 N/m
and ω is
ω = 
ω = 
ω = 9.9
so here position w.r.t time is
y = 0.05 × cosωt
y = 0.05 × cos(9.9)t
so position as a function of time is y = 0.05 × cos(9.9)t
its B 0.225kPa using the formula p=f/A then change the pascals into kpa
Answer:
hello your question is poorly written and I have tried to understand it hence I will give a general diagram as related to your question
answer : attached below
Explanation:
Attached below is the required diagram of the situation you are trying to describe
let the wide receiver be ; W
Corner back = C
westward velocity = Vw
eastward velocity = Vc
at initial position X = Xw
x = 0 ( initial position )
answer
Height at which kiwi reach=1.2m
Solution
In this question we have given
mass of apple, 
mass of kiwi,
height from which apple is dropped,
Let the height at which kiwi reached is 
here,
We will apply law of conservation of energy
it means,
potential energy of kiwi= potential energy of apple
......(1)
here g is gravitational acceleration
put values of
and
in equation 1

therefore, Height at which kiwi reach=1.2m
