Thrustssc, the world's first supersonic car, accelerates from rest to 1000 km/h in 16 s.

The acceleration of the supersonic car is .

Explanation:

Given that,

Initial speed of the supersonic car, u = 0

Final speed of the supersonic car, v = 1000 km/h =

Time taken, t = 16 s

To find,

The acceleration of the car.

Solution,

The change in velocity per unit time of an object is called its acceleration. It is given by :

So, the acceleration of the supersonic car is . Therefore, this is the required solution.

a sonic boom is a loud boom that breaks the sound barrier

explanation:

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
