A boat is able to move through still water at 20 m/s. It makes a round trip to a town 10 km upstream. If the river flows at 5m/s

Nataly_w [17]

Answer:

The time required for this round trip is 1066.66 s

Explanation:

Given;

velocity of boat through still water, v₁ = 20 m/s

distance moved by the boat, d = 10 km = 10,000 m

velocity of the river, v₂ = 5 m/s

time = d / v

The boat made two journeys which formed the round trip.

During the first part of the journey, the boat moves upstream in opposite direction to the flow of the river and the resultant velocity is calculated as;

Resultant velocity = 20 - 5 = 15 m/s

Time for this journey, = 10000/ 15 = 666.66 s

During the second part of the journey, the boat moves downstream in the same direction to the flow of the river and the resultant velocity is calculated as;

Resultant velocity = 20 + 5 = 25 m/s

Time for this journey, = 10000/ 25 = 400 s

Total time for the trip = 666.66 s + 400 s = 1066.66 s

The momentum change of the running back is - 664.2 kg m/s or 664 west.

<u>Explanation:</u>

Momentum is defined as the change in velocity of any object along with its mass. So mathematically, momentum can be derived using the product of mass with the change in velocity.

$\text { Momentum change }=m \times \Delta v$

As here mass is given as 82 kg and the initial velocity was 5.6 m/s and final velocity is 2.5 m/s.

Initial Momentum = $m \times \text { initial velocity }=82 \times 5.6=459.2 \mathrm{kg} \mathrm{m} / \mathrm{s}$

Final Momentum = $m \times \text { final velocity }=82 \times(-2.5)=-205 \mathrm{kg} \mathrm{m} / \mathrm{s}$

Momentum change = Final Momentum - Initial Momentum

Momentum change = - 205 - 459.2 = - 664.2 kg m/s or 664 west

Thus, the changing momentum is -664.2 kg m/s. The negative sign indicates that the momentum is acting in the opposite direction on changing in the direction of velocity.
