Explanation :

The momentum of an object is defined as the product of its mass and the velocity with which it is moving.

The law of conservation of momentum states that the total momentum of a system remains conserved when the external force acting on it is equal to zero.

Mathematically, it can be written as :

p_i=p_f

where,

p_i and  p_f are the initial and the final momentum.

Hence, it is the required solution.

A 110 kg quarterback is running the ball downfield at 4.5 m/s in the positive direction when he is tackled head-on by a 150 kg l
melisa1 [442]

Answer:

v_f=-0.29\frac{m}{s}

Explanation:

The principle of conservation of momentum, states that if the sum of the forces acting on a system is null, the initial total momentum of the system before a collision equals the final total momentum of the system after the collision. The collision is completely inelastic, which means that the players remain stick to each other after the collision:

p_i=p_f\\m_1v_1+m_2v_2=(m_1+m_2)v_f\\v_f=\frac{m_1v_1+m_2v_2}{(m_1+m_2)}\\\\v_f=\frac{(110kg)4.5\frac{m}{s}+150kg(-3.8\frac{m}{s})}{(110kg+150kg)}\\v_f=-0.29\frac{m}{s}

Suppose you drive an average of 25 miles a day, for a total of 60 years in a lifetime. The total distance you would have covered
Ahat [919]

The total distance you would have covered is equivalent to going around the earth 22 times.

<h3>Total distance traveled</h3>

The total distance traveled at a given speed and time of motion is calculated as follows;

Distance = speed x time

Distance = \frac{25 \ miles}{day} \times \frac{365 \ days}{1 \ year} \times 60 \ years\\\\Distance = 547, 500 \ miles

<h3>Distance round the Earth</h3>

The distance round the earth or circumference of the earth of the earth has been given as 25,000 miles

<h3>Number of times round the earth</h3>

n = \frac{547,500}{25,000} \\\\ n = 21.9 \ times \ \approx 22 \ times

Thus, the total distance you would have covered is equivalent to going around the earth 22 times.
