Question

A particle accelerates from rest with an acceleration of 8.0m/s2. Calculate its velocity after 150s. What kinematic formula must be used to solve this problem?

Sample answer format: c=a+b (no spaces in between). If subscript is needed type it as it is , for example cf=ai+b.

Answer 1

Final velocity: 1200 m/s

Step-by-step explanation:

Formula:
`\overline{a} = (v - v_0)/(t) = (\Delta v)/(\Delta t)`

Where:

a = average acceleration

v = final velocity

vo = starting velocity

t = elapsed time

Here the final velocity is unknown which we have to find. The initial is 0 m/s

as it was at rest. The time taken: 150 seconds. Acceleration given 8.0 m/s²

using the formula:

`\overline{a} = (v - v_0)/(t)`

`8 = (v - 0)/(150)`

`v = 1200` m/s
