If a 20 N force acts on a 10 kg object for 0.5 seconds. If the object starts at rest, what would it’s new p (momentum) and v (velocity) be?

Explanation:

From Newton's 2nd Law, we have . We can use this to find the acceleration of object after 20 N (force) is applied to the 10 kg object.

Substituting given values, we have:

Now that we have acceleration, we can find the final velocity of object (after 0.5 seconds) using the following kinematics equation:

, where is final velocity, is initial velocity, is acceleration, and is time.

Solving for final velocity:

The momentum of an object is given as . Since we've found the final velocity and mass stays constant, we have:

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
