How Do You Determine Maximum Acceleration from a Velocity-Time Graph?

[ProBasket]

The graph shows the velocity v of a sports car as a function of time t . Use the graph to answer the following questions.

1.) Find the maximum acceleration a_max of the car
Express your answer in meters per second squared to the nearest integer.
a_max= _____________________ m/s^2


from the graph, should the acceleration be around 55m/s? but the answer must be in m/s^2, should am i suppose to convert it first? I'm new to physics, so all of this is pretty confusing.

Is this from a non-calculus based physics class?

velocity is in m/s is it not? Acceleration is the change of velocity with respect to a change in time or \Delta v/\Delta t. Loot athe the graph and equate changes in velocity with their corresponding change in time.

it's a cal-based class.

how would i find the changes in velocity? it's all over the place. and for time, would the change in time be 1?

If this is a calculus based class then you should know that acceleration is the slope of a velocity function.

given a function y(x) then the slope of said function is dy/dx. Given a function of v(t) then the slope is dv/dt which is acceleration.

Think slope and grab a ruler.
