The velocity of a car traveling in a straight line increases from 0 meters/second to 30 meters/second in 8 seconds. what is the average acceleration of the car?

Answer :

Explanation :

Initial velocity of the car, u = 0 m/s

Final velocity of the car, v = 30 m/s          

Time taken, t = 8 s

Average acceleration of the car is defined as the change in velocity divided by time.

Hence, this is the required solution.                                              

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

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
