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

need to see circuit to get time constant

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.
