Answer 1

Momentum is expressed as the product of mass and the velocity of an object. It refers to the quantity of motion that an object possess. From the choices listed above the correct answer is option D, 9.5 x 10^2 kilograms*meters/seconds.

Momentum = m(v)
Momentum = 75 kg (45 x 1000 / 3600 ) m/s
Momentum = 950 kg m / s
