(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

​

Answer 1

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

Answer: 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.

Answer: 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

Answer: 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?
