Question

An object accelerates at 10 m/s2. If its starting velocity is 20 m/s and it travels for 30 seconds, what is its final velocity?

Answer 1

Answer:

320m/s

Explanation:

Step 1: State your values

s= NOT NEEDED

u=20m/s

v=?

a=10m/s²

t=30 seconds

Step 2: Find a suitable suvat equation:

v=u+at

Step 3:

subsitute values into equation:

?=20+(10x30)

20+300

320m/s
