Answer 1

What do you think it is?

Answer 2

I dont think that is correct

Answer 3

kinematics equation

x = (vf + v0)/2 * t

the distance, x, is the area under the velocity/time curve. this is given as 10, so x = 10.

v0 is the initial velocity (0, from the graph)
vf is the final velocity (2, from the graph)

t is time

plug in the appropriate quantities and solve for t
