An object accelerates from 10 m/s to 30 m/s in 5 seconds. What is the acceleration? (a = change in velocity ÷ time)
Answer
4 m/s²
How to solve it
1
Initial velocity: 10 m/s
2
Final velocity: 30 m/s
3
Change: 30 - 10 = 20 m/s
4
Time: 5 s
5
Acceleration: 20 ÷ 5 = 4 m/s²
Hints
Find change in velocity
Divide by time
