Yes, if we know the Earth's mass
Explanation:
The momentum of an object is a vector quantity given by the equation
where
m is the mass of the object
v is its velocity
In this case, we are asked if we can find the velocity of the Earth by starting from its momentum. Indeed, we can. In fact, we can rewrite the equation above as
Therefore, if we know the momentum of the Earth (p) and we know its mass as well (m), we can solve the formula to find the Earth's velocity.

"An object weighs about two times as much on Jupiter as on Neptune." Hope this helps :)
We know, a = v/t
Here, a = 5 m/s²
v = 50 km/h= 13.88 m/s
Substitute their values into the expression:
5 = 13.88 / t
t = 13.88/5
t = 2.78 sec
Now, we know, v = d/t
13.88 = d/2.78
d = 13.88 * 2.78
d = 38.53 meter
In short, Your Answers would be:
i) It will take 2.78 sec
ii) It will travel for 38.53 m after a brakes applied.
Hope this helps!
