Answer: PE = 800j, KE = 800J

Explanation:

To calculate the potential energy, we use the formula  

Potential Energy = Mgh

M = 20kg, g = 10m/sˆ2 , h = 4m

=20 × 10 × 4

=800J

At the maximum height  S = 4 and the initial velocity u = 0 The acceleration g = 10m/sˆ2

Using the third equation of motion

vˆ2 = uˆ2 + 2as

= 0ˆ2 + 2 × 10 ×  4

vˆ2 = 80

Kinetic Energy (KE) is given by  

KE = ½ mvˆ2

= ½ × 20 × 80

=800J

Utilitarians believe in:______.
kkurt [141]

Answer:

only one absolute moral rule:

the principle of utility

Explanation:

The principle of utility holds that actions or behaviors are morally right or wrong depending on if they promote happiness or pleasure.

They opine that an action is wrong if it brings displeasure and unhappiness and are against absolute moral codes that classify specific actions or behaviors as right or wrong. Utilitarians therefore believe that pain or pleasure can be objectively measured and quantified.
