If the mass of an object is 8 kg and its momentum is -80 kgm/s, what is its velocity?
a. 10 m/s
b. 12 m/s
c. 8 m/s
d. -10 m/s

An object's momentum is the product of its mass and its velocity:

p = mv

p is its momentum, m is its mass, and v is its velocity.

Given values:

p = -80kg×m/s

m = 8kg

Plug in these values and solve for v:

-80 = 8v

v = -10m/s

Choice D

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.
