Answer:
2.91 x 10¹² sec
Explanation:
d = distance of nearest star, Proxima Centauri = 4.3 ly = 4.3 x 9.46 x 10¹⁵ m
v = speed of new horizon probe = 14 km/hr = 14000 m/s
t = time taken for the new horizon probe to reach nearest star, Proxima Centauri = ?
Using the equation
d = v t
Inserting the values given
4.3 x 9.46 x 10¹⁵ = (14000) t
t = 2.91 x 10¹² sec
Answer:
10m/s
Explanation:

Since there is no initial velocity as the object is dropped, you can write the following equation:

Now that you know how long the fall took, you can use another physics equation to find the velocity at that point.

Since there once again is no initial velocity, you can rewrite this as:
