A car moves at 20 meters in 2 seconds. What is the momentum of the car if it has a mass of 3,000 kg?

A football player runs across the field for a tackle. He has a momentum of 1,120 kg x m/s and is moving down the field at 10 m/s what is the mass of the player?

Anything helps I've looked for help and tried doing these I just don't get it!

momentum=mass*velocity=2000*2/20 kgm/s

b. momentum=mass*velocity
mass=momentum/velocity

car: velocity = 20/2 m/s = 10 m/s

momentum = mass * velocity = 3000*10 kg x m/s

player: mass = momentum/velocity = 1120/10 = 112 kg.

To calculate momentum, you need to use the equation:

Momentum (p) = mass (m) × velocity (v)

For the first question, you are given the velocity (20 m) and the mass (3,000 kg). Plugging these values into the equation, you get:

Momentum = 3,000 kg × 20 m/s = 60,000 kg·m/s

Therefore, the momentum of the car is 60,000 kg·m/s.

For the second question, you are given the momentum (1,120 kg·m/s) and the velocity (10 m/s). We need to find the mass (m) using the same equation:

Momentum = mass × velocity

Substituting the given values, we get:

1,120 kg·m/s = mass × 10 m/s

To isolate the mass, divide both sides of the equation by 10 m/s:

mass = 1,120 kg·m/s ÷ 10 m/s = 112 kg

Therefore, the mass of the football player is 112 kg.

Remember, the formula for momentum is p = m × v, where p is the momentum, m is the mass, and v is the velocity. By plugging in the given values and solving for the missing variable, you can find the answer.
