Answer:
Newton's third law of motion.
Explanation:
Every action has an equal and opposite reaction.
Answer:
Explanation:
Total weight
My weight+weight of belongings
660+1100=1760N.
a. Work done by the elevator to travel a total height of 15.2m
Using newton law of motion
ΣF = ma
There are only two forces acting upward, the weight and the reaction by the elevator
Also note it is moving at constant velocity then, a=0
N - W=0
Then, N=W
N=1760N
So, workdone is given as
Wordone, =force × distance
Work done=1760×15.2
W=26,752J
W=26.752KJ
b. Work done on me alone is still need to go through the same process but will remove the weight of the belonging
Therefore,
Weight now = 660N
And using the same equation of motion
ΣF = ma
Comstant velocity, a=0
N - W=0
N=W
N=660N
Then, workdone
W=F×d
W=660×15.2
W=10,032J
W=10.032KJ
C. a lack of accurate results

Answer:
700 m
Explanation:
Given:
v₀ = 0 m/s
a = 14 m/s²
t = 10 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (0 m/s) (10 s) + ½ (14 m/s²) (10 s)²
Δx = 700 m
When one mass accelerates another mass the later mass is felt as weight or force.For example, if you push two objects under the same conditions with the same amount of force, the object with the lower mass will accelerate faster.
Hope this helps
