Explanation:
We can measure the length, weight, and capacity (volume) of any given object.
Answer:
b because we apply Hooke's law
Explanation:
Hooke's law
We use a fundamental kinematic equation as follows:
V = Vo + g*t.
<span>Tr = (V-Vo)/g = (0-10)/-10 = 1 s. = </span><span>time to reach max. height </span>
<span>Tf = Tr = 1 s. = Fall time or time to fall back to edge of bldg. </span>
<span>3-Tr-Tf = 3-1-1 = 1 s. Below edge of bldg. </span>
<span>d = Vo*t + 0.5g*t^2. </span>
<span>d = 10*1 + 5*1^2 = 15 m. <---- OPTION C</span>
Answer:
speed of the arrow as it leaves is 41.05 m/sec
Explanation:
We have given mass m = 0.285 kg
Average force F = 182 N
Distance traveled d = 1.32 m
We know that work done = force distance
Sp work done =
Now according to work energy theorem work done will be equal to kinetic energy
So
v = 41.05 m/sec
So speed of the arrow as it leaves is 41.05 m/sec
