1 Answer
Acceleration
Explanation:
Use the equation:
Where
s is the distance covered, s = 50m
Rearrange to make
Acceleration
Acceleration
Acceleration
Hint!
Rather than trying to remember:
Visualise s as the area under a speed Vs time graph. Which for this case would look like this:
graph{1.75x + 15 [-0.5, 4, -5.12, 25]}
