Question

A hummingbird beats its wings 24 times per second.

(a) Calculate the number of times the hummingbird beats its wings in one hour.

(b) Write your answer to part(a) in standard form

Answer/Explanation

(a)Using unitary method ,

1 sec = 24 times

60\(\times\) 60 sec = 24\(\times\)3600

 = 86400 times

(b) Standard form basically means writing the numbers in the power of 10 

So, 86400 in standard form is : 8.64\(\times 10^4\)

Question

A train leaves Barcelona at 21:28 and takes 10 hours and 33 minutes to reach Paris.
(a) Calculate the time the next day when the train arrives in Paris.

(b) The distance from Barcelona to Paris is 827 km.
Calculate the average speed of the train in kilometres per hour.

Answer/Explanation

(a) 21:28 is 9:28 pm  in 12 hours format clock

So, Adding 10 hours 33 minutes to 9:28 pm gives 8:01 am 

So, the train will be reaching by 8:01 ,the next day

(b) Average speed=\(\frac{ Total distance}{Total time}/)

Now , 10 hours 33 minutes= 10+33/60 minutes=10.5 hours 

So, putting it into formula :

Average speed= \(\frac{ 827km}{10.5hours}/)

=78.38 km/hour

Question

 

The diagram shows the speed-time graph of a train journey between two stations.
The train accelerates for two minutes, travels at a constant maximum speed, then slows to a stop.
(a) Write down the number of seconds that the train travels at its constant maximum speed.

(b) Calculate the distance between the two stations in metres.

(c) Find the acceleration of the train in the first two minutes.
Give your answer in m/s2

Answer/Explanation


Distance is I= ut+\(\frac{1}{2}a t^2\)

=0(120)+\(\frac{1}{2}\times\frac{5}{8}\times 120\times 120

900 m

Distance is II= 15m/s\(\times (8\times 60\)

15\(\times 480\)

=7200 m 

Similarly , Distance is III=180-450

= 1350 m 

Total distance =900+72300+1350m

= 9450 m

(c) a=\(\frac{\Delta V}{\Delta V}\)

a=\(\frac{V_f-V_i}{T_f-T_i}\)

a=\(\frac{15-0}{(2.60)-0}\)

=\(\frac{1}{8}\) m/\(s^2)\)

Question

The speed-time graph shows this voyage.

(a) Calculate the total distance travelled by the ship.

(b) Calculate the average speed of the ship for the whole voyage.

Answer/Explanation

(a) Distance = speed \(\times time\)

= 156

(b) 12

Question

A person in a car, travelling at 108 kilometres per hour, takes 1 second to go past a building on the side of the road. Calculate the length of the building in metres.

▶️Answer/Explanation

To calculate the length of the building. We can use the formula,
Distance \(= Speed \times Time\)
Given that the speed of the car is 108 kilometers per hour and the time taken to go past the building is 1 second, we need to convert the speed from kilometers per hour to meters per second.
1 kilometer = 1000 meters
1 hour = 3600 seconds
Converting the speed,
108 kilometers per hour\(=\frac{108\times 1000 m}{3600 s}=30ms^{-1}\)
Now, we can calculate the distance covered by the car in 1 second:
\(Distance = Speed\times Time = 30 ms^{-1}\times 1s =\) 30 meters
Therefore, the length of the building is 30 meters.
