Question

If function of acceleration vs time is, a = 6t then find out
average acceleration from t = 1 to 2 s -
(1) 9 m/s2 (2) 6 m/s2 (3) 3 m/s2 (4) 2 m/s2​

Answer 1

Answer:

9 m/s²

Explanation:

At t = 1 sec, a = 6 m/s²

At t = 2 sec, a = 12 m/s²

Average acceleration = (6 + 12)/2

=9 m/s²

Answer 2

Answer:

9 m/s²

Explanation:

Average acceleration refers back to the fee at which the rate changes. We divide the extrade in speed with the aid of using an elapsed time to discover the common acceleration of anything. For instance, if the rate of a loopy ball will increase from zero to 60 cm/s in three seconds, the common acceleration of the ball might be 20 cm/s/s. If the rate of a marble will increase from zero to 60 cm/s in three seconds, its common acceleration might be 20 cm/s2. Meaning that the marble's speed will move up with the aid of using 20 cm/s every second.

At t = 1 sec, a = 6 m/s²

At t = 2 sec, a = 12 m/s²

Average acceleration = (6 + 12)/2

=9 m/s²
