Acar is moving northeast at a velocity of 10 meters per second. four
seconds later it's going 30 meters per second. what was the car's average
acceleration during this time?
a) 5 m/s
b) 5 m/s²
c) 5 m/s² northeast
d) 20 m/s² northeast

The average acceleration of car during this time is 5 Northeast.

Option C

Explanation:

The acceleration exerted by an object is the rate of change in velocity the object undergoes with respect to time. Average acceleration is the measure of variation in acceleration in a given interval of time.

Here, final velocity is 30 m/s and initial velocity is 10 m/s. The final velocity is attained by the car after 4 s. Thus, the average acceleration will be

So, the average acceleration is 5 and as the car was moving in the northeast direction, the average acceleration will also be exerting in the northeast direction only.

the correct choice is a .

like poles repel so keep pushing north to north and repels funny to see this
