Answer:
Step-by-step explanation:
labor cost = 20 * h = 20h
Total cost = 100 + 20h
Answer:
Step-by-step explanation:
Let d be the diameter of the wheel.
Circumference = πd
(35.325 m)/(25 revolutions) = (1.413 m)/revolution
πd = 1.413
d = 1.413/π = 0.45 m
Answer:
-8
Step-by-step explanation:
x less than or equals to -8
The answer is 12 J.
The kinetic energy (KE) of an object is expressed as the product of half of the mass (m) of the object and the square of its velocity (v²):

The unit of the kinetic energy is Joules (J = kg · (m/s)²).
It is given:
m = 1.5 kg
v = 4 m/s
It is unknown:
KE = ?
