On a horizontal road, a car is traveling West at a constant speed of 11.4 m/s . After 16 s , it has rounded a corner and is now heading North at a constant speed of 16.0 m/s .
What is the magnitude of the car's average acceleration during this 16 s time interval?
0.29 m/s2 |
1.2 m/s2 |
0 m/s2 |
1.7 m/s2 |
As we know that the acceleration is the rate of change of an object's speed. In other words we can say that acceleration is something which tells us how fast velocity of an object changes.
We can find the acceleration of a moving object by the formula given below:
In this particular case, the speed is constant & the surface too doesn't has slope.
According to question, the values of initial & final velocities are given below :
Which can be calculated as below :
So, the actual acceleration is 0.2875 metre per second squared, which is in round figures is 0.29 metre per second squared, which the preferred answer.
