A car has a mass of 8000 kg and a kinetic energy of 24,000 J. What is its
2 answers:
AnswerB . 2 . 4 m / s
Explana tions ;
2 4 0 0 0 = 1 / 2 × 8 0 0 0 × v ^ 2
2 4 0 0 0 / 4 0 0 0 = v^ 2
√ 6 . = v
v = 2 . 4
Answer:
2.4
Explanation:
48,000/8000=6
square root of 6 = 2.44948974278
so 2.4

Answer:
Pressure = 5 x 10⁶ Pa
Explanation:
Given:
Height of building = 512 m
Find:
Pressure
Computation:
P2 = P1+dgh
P2 = 1 + (1000)(9.8)(512)
P2 = 51.2 atm
Pressure = 5 x 10⁶ Pa
