Did you know conventional argult culture has increased greenhouse gas emissions, soil erosion, water pollution, and threatened humans health. Let’s stop this from harming our environment and take action about this today. Organic farming has a smaller carbon footprint, conserves and builds soil, replenishes natural ecosystems for cleaner water and air, all with a toxic pesticide residues.

The momentum of the body is 12 m/s.
<h3>What is momentum?</h3>
Momentum is the product of the mass of a body and velocity. According to Newton's second law, the rate of change of momentum is equal to the impressed force.
The details required to answer the first two questions are missing hence we can't answer those questions. For the last question;
p = mv
m = mass
v = velocity
p = momentum
v = p/m
v = 72,000 kgm/s/6,000 kg
v = 12 m/s
