Question

What is the acceleration of this object ?

Answer 1

-2.5

Step-by-step explanation:

just did this one

Answer 2

-2.5 m/s^2

Step-by-step explanation:

From a velocity-time graph, the acceleration can be determined by finding the gradient of the straight line graph.

Acceleration=(Change in velocity)/(time)

Where change in velocity = final velocity-initial velocity.

Hence, from the graph,

we can see (10-40)/12 = -2.5
