PLEASE HELP ASAP!
1. What is the velocity of a 50 kg teen running with 250 kg*m/s of momentum?
2. What is the mass of a truck with 20500 kg*m/s of momentum that’s moving at 205 m/s?

Velocity of the teen = 5m/s

Mass of the truck = 100kg

Explanation:

Momentum can be found with the equation

P = m * v

Where P is momentum in kg*m/s, v is velocity in m/s and m is mass in kg.

Substitute in our values and solve for the unknowns

1.) P = m * v

250 = 50 * v

Divide both sides of the equals by 50 to solve for v

250/50 = v * 50/50

v = 5m/s

2.) P = m * v

20500 = m * 205

Divide both sides of the equals by 205 to solve for m

20500/205 = m * 205/205

m = 100kg
