1 answer:
Given :
A school bus moves down a road, dropping off students after school.
The bus slows down from a speed of 15 meters per second to a full stop over a distance of 55 meters in 11 seconds.
To Find :
The average speed, in meters per second, of the school bus while the bus is slowing down.
Solution :
Initial velocity, u = 15 m/s.
Distance travelled, d = 55 m.
Time taken, t = 11 s.
Final velocity, v = 0 m/s.
We know, average velocity is given by :
Therefore, average velocity is 5 m/s.
Hence, this is the required solution.

In a series circuit the total current is the same throughout resistors and so:
The voltage is distributed throughout the resistors and so:
and the total resistance can be calculated by adding up the resistors resistance:
First thing is to calculate the total resistance and so:
And by Omh's law V=IR we have:
And so the total current of the circuit is 1.2 amps i.e. 1.2 A.

<u>Vertical Launch Upwards</u>
In a vertical launch upwards, an object is launched vertically up from a height H without taking into consideration any kind of friction with the air.
If vo is the initial speed and g is the acceleration of gravity, the maximum height reached by the object is given by:
The object referred to in the question is thrown from a height H=0 and the maximum height is hm=77.5 m.
(a)
To find the initial speed we solve for vo:
(b)
The maximum time or the time taken by the object to reach its highest point is calculated as follows:
