What is the formula to find momentum

P=mv

Momentum of any object is defined as the multiple of velocity of an object and the mass of the object. So we can easily deduce that momentum is directly proportional to velocity of an object if the mass of the object remains constant. So it can be seen that if the mass of the object does not change then any change in velocity is bound to have an effect on the momentum of the object. We can easily write the equation as momentum= mass x velocity.

If there was no gravity then their would be no downword force on the football to have it return the the grownd, and if there was no friction (mainly air friction) then there would be no opposing force the stop the ball from moving through the air allowing the ball to travle ∞.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
