Answer:
F (force of gravity) = M (mass of an object) × G (acceleration due to gravity)
Step-by-step explanation:
Force of gravity (F) = Mass (M) × Gravitational acceleration (G)
The weight of an abject is equal to its gravitational force!
Answer:
Sample Response: Jason needs to substitute the value he found for x in the original equation. Then he needs to use order of operations to simplify. If the result is a true statement then Jason’s solution is correct.
Step-by-step explanation:
well, put the 2 on the right side of the 3, and divide it's simple, 3 goes into 2, one time, now put the 1 over the 2, and put the 3 under the 2, and then subtract 2 from 3.
2-3= 1, how any times does 3 go into 1, it doesn't. so put a 0 next to the 1
and how many times does 2 go into 10. five times. so your answer in 1.5
Let s = the smaller one of the two.
Since they are consecutive, the second one is (s + 1)
Since they are natural numbers, they cannot be negative.
We know that s(s + 1) = s + (s + 1) + 155
So:
s(s + 1) = 2s + 156
s^2 + s = 2s + 156
s^2 - s - 156 = 0
(s - 13)(s + 12) = 0
From this, it looks like s can be either 13 or -12. But since it's a natural number, it cannot be negative. So, it is 13.
s was the smaller one. The larger one is s + 1 = 14
Check: 13*14=182=13+14+155

Answer:
6 m/s
Step-by-step explanation:
The formula for kinetic energy is ...
KE = (1/2)mv² . . . . m is mass
Filling in the given values, we can solve for v.
1440 J = (1/2)(70+10 kg)v^2
(1440 J)/(40 kg) = v^2 = 36 m²/s² . . . . m is meters
v = √(36) m/s = 6 m/s
The man is moving at 6 meters per second.
_____
In terms of units analysis, the joule (J) is a derived unit equal to ...
1 J = 1 kg·m²/s²
