1. Which object is moving faster in the graph below? Justify your answer. А
Position (m)
Time (s)

I assume you mean the acceleration you want to reach is 4.6 m/s^2, and it takes 10 s linearly to get there.

Then this will be an integration problem, you need to integrate the velocity in form of acceleration with respect to time.

So a = 0.46t, where a is acceleration, t is time

So your velocity at time t equals to: a*t = 0.46t^2

So at t=10, V = 0.46 * 10^2 = 46 m/s
