Answer:
well sound waves interact with our ears and light interacts with our vision
Explanation:
Potential Energy = mgh,
where m = mass in kg, g ≈ 10 m/s², h = height above ground = 8 m
PE = mgh
= 70*10*8 = 5600 J
Because of the gravitational pull when we go up the gravity pulls u down
Answer:
10044 N
Explanation:
The acceleration of the cab is calculated using the equation of motion:

<em>v</em> is the final velocity = 0 m/s in this question, since it is brought to rest
<em>u</em> is the initial velocity = 10 m/s
<em>a</em> is the acceleration
<em>s</em> is the distance = 35 m

Since it accelerates downwards, its resultant acceleration is

<em>g</em> is the acceleration of gravity.

The tension in the cable is
