Answer» (a)The total number of divisions on horizontal axis for 2 s is 5.The total number of divisions on vertical axis for 2 m/s is 3.The total DISPLACEMENT of the car during these two seconds will be given as the area under all these squares.The area under the (3×5) squares is given as:A 15 =2×2 = 4So, the area under one small square is :A 1 = 154 Now, the area under the graph for 4 sec is:the number of squares under the graph is :n=57 small squares + 6 half small squaresSo, total number of squares =60.So, the distance TRAVELED by the car is the area under the curve.S=60× 154 S=16 mExplanation:plz MARK as brainliest if u find the ANSWER helpful |
