Un cuerpo de 60 kg se encuentra a una distancia de 3.5 m del otro cuerpo, de manera que entre ellos se produce una fuerza de 6.5
aev [14]

Answer:

1989.6Kg

Explanation:

The computation of the mass of the other body is given below:

As we know that

F = G × m1 × m2 ÷ r²

Here the G would have the constant value i.e. 6.67 × 10^-11Nm² / kg².  

Now

6.5 × 10^-7N = 6.67 × 10^-11Nm² / kg² × 60Kg × m2 / (3.5m) ²

m2 = (F × r²) / (G × m1)

m2 = (6.5 × 10^-7N × (3.5m) ²) ÷ (6.67 × 10^-11Nm² / kg² × 60Kg)

= 1989.6Kg

Determine the kinetic energy of a 1000-kg roller coaster car that is moving with a speed of 20.0 m/s.
Nookie1986 [14]

Answer:

The kinetic energy is 200.000 Joule (200KJoule)

Explanation:

We use the formula of kinetic energy:

Ec =1/2 x  m x v^2

Ec=1/2 x 1000kg x (20m/s)^2 = 200.000Joule

200.000J/1000KJ/J=200 kJoule
