for acceleration we can define that rate of change in velocity is know as acceleration
So whenever velocity of train is changing with time we can say train is accelerating
Now here if initially train is standstill then after some time its speed is 5 m/s
so here the train is accelerated first time
Then on straight path its speed changed from 5 m/s to 10 m/s so here train gets accelerated second time
After this train chugged around a curve with same speed 10 m/s
SO here since train is moving in curve so here its direction of velocity is continuously changing and this type of acceleration is known as centripetal acceleration
SO this is accelerated Third time
Then its speed decreases and it comes to speed of 5 m/s from 10 m/s
So here it is acceleration of train for Fourth time
Then finally train comes to stop so again its speed changed from 5 m/s to 0
so this is acceleration of train Fifth time
So total train will accelerate 5 times in whole path
Answer:
No, they are not because when you stretch the rubber band you are deforming it but with the spring it is made to go up and down.
Explanation:
Answer:
Acceleration of truck is smaller as compared to the car
Explanation:
We can use newtons second law to solve this
Net Force = mass × acceleration
With the sane force applied and a larger mass of truck, acceleration of truck would be smaller as compared to the car
B. The suns gravity

Answer:
1.333 beats/s
It takes 0,755 s per beat
Explanation:
If we want to convert this frequency from beats per minute to beats per second, we have to do the following:

This means that in 1 second David has 1.333 heart beats.
Now, if we want to know how long does it take between heart beats, we can use the mathematical<u> Rule of Three</u>:
1.333 beats ---- 1s
1 beat ------ ?

This means there are 0.75 s between heart beats
