Answer:
Explanation:
When the velocity of an object changes, it would experience an impulse. If the mass of the object stays the same, and that the object moves along a line, the value of the impulse would be:
, where
- is the mass of the object, and
- is the change in the velocity of the object.
On the other hand, the change in the object's velocity can be found with the equation:
.
Note that if is in and is in , the unit of would be .

.
Note that and are of opposite signs. The reason is that the object's velocity has changed direction in this period.

Answer:
approximately 0.00504 kWh
Explanation:
This electrical energy and is measured in kWh.
For 5 minutes and 20 seconds of use, it is 0.06 W x 0.084 h = 0.00504 kWh.
<u><em>Note</em></u>: 60W = 0.06kW; 5min 20sec = 0.083(8) ≈ 0.084 hour
Thank you for posting your question your question here. Below is the solution:
time = 3.00 / 1.75
<span>time = 1.714 </span>
<span>now </span>
<span>distance = (initial velocity + final velocity) / 2 * time/ 1 </span>
<span>Hence</span>
<span>3 = ( 1.75 + final velocity) / 2 * 1.714 </span>
<span>3.5 - 1.75 = final velocity </span>
<span>Therefore, the final velocity is 1.75 m /s</span>
