Question

3) The position of an object in motion relative to the x-axis is denoted by x = a + bt ^ (2). Where a = 8.5 m. b = 2.5 ms ^ (- 2) and is measured in seconds. What will be its velocity at t = 0? What will be the average velocity between 2.0 s and 4.0 s?​

Answer 1

Answer:

3.6

Explanation:

because the velocity measures in seconds

Answer 2

Answer velocity at t=0 is 0

And Average Velocity =15m/s
