(i)Draw the shape of speed-time graph representing the above sets of observations.

(ii) Find the acceleration of the car.

(iii)When will you say a body is in uniform

(i)Draw the shape of speed-time graph representing the above sets of observations.

on a graph you would wright these points as (0,5),(10,10),(20,15),(30,20),(25,40),(50,30). I recommend using desmos.com or drawing a graph on a paper for this one.

(ii) Find the acceleration of the car.

To find the acceleration you will need to find the rate in which the car moves

(iii)When will you say a body is in uniform

As for whether this has a uniform it means does it have a variable or function for example every time this car gets faster how does it change?
