QUESTION:
Which is greater, an acceleration from 25 km/h to 30 km/h or one from 96 km/h to 100 km/h if both occur during the same time?
ANSWER:Solution Step 1 of 4 Acceleration is the rate of change of velocity or it is the ratio of change in velocity to the time taken for the change. It tells about, how fast the object gains or losses its speed. That is, change in velocity(m/s) a = time taken(s) = t Where a is the acceleration, v is the change in velocity in the given interval of time t. Acceleration is a vector, it has both magnitude and direction.
