2.Kinetic energy =25 units</h2><h2>
3.Kinetic energy =5 0 units</h2><h2>
4.Kinetic energy = 200 units</h2>
Step-by-step explanation:
1.
Kinetic energy =
Here m = 1500 kg and v = 14 meter / second
Kinetic energy = = joule =147000 joule
2.
Here m = 2 unit and v = 5 units
Kinetic energy = = units =25 units
3.
Here m= 2 units and v = 5 units
Kinetic energy = ==5 0 units
4.
Here m= 2 units and v= 10 units
Kinetic energy ==units = 200 units
Answer:
40
Step-by-step explanation: I just guesstimated a number and divided 36 by 40 to get .9 which means 90%
2/7x - 2/5x = 8
multiply both sides by 35
= 10x - 14x = 280
combine 10x and 14x
= -4x = 280
divide both sides by -4
x= -70
Presumably you mean 555 as a number in base 10.
We have
555 = 5 • (100 + 10 + 1)
… = 5 • (4 • 25 + 2 • 5 + 1)
… = 5 • (4 • 5² + 2 • 5¹ + 1 • 5⁰)
… = 4 • 5³ + 2 • 5² + 1 • 5¹
… = 4210₅
