jill's car has a maximum acceleration of 8.7 miles per hour per second. how many seconds does it take her to acceleration from 0
amm1812
T = ?
v1 = 0mph
v2 = 60mph
a = 8.7mph/s

a =  \frac{v2 - v1}{t}&#10; \\ t =  \frac{v2-v1}{a}&#10; \\ t =  \frac{60mph - 0mph}{8.7mph/s}&#10; \\ t = 6.90s

Therefore, it takes 6.90 seconds for Jill to accelerate from 0 to 60 miles per hour.

A binary star system consists of two stars of masses m1 and m2. The stars, which gravitationally attract each other, revolve aro
zubka84 [21]

Answer:

 a₂ = m₁ / m₂ a₁

Explanation:

For this exercise we note that the attraction between the two stars is an action and reaction force, therefore it has the same magnitude, but it is applied to each of the bodies

Let's apply Newton's second law on the star 1

     F₁ = m₁ a₁

Newton's second law in star 2

       F₂ = m₂ a₂

       | F₁ | = | F₂ |

      m₁  a₁ = m₂  a₂

      a₂ = m₁ / m₂ a₁
