Hello please answer this question correctly and I'll give you a brain list

ANSWERS

>>>>>>>>>>>>>>>

(i) The distance travelled = Area under the graph

=> Distance in first two seconds = Area of triangle ABE

=> Distance = 1/2 × 2 × 15

=> 15 m

>>>>>>>>>>>><<><<>

(ii) Acceleration = slope of graph

=> Acceleration = 15 / (6-5)

=> Acceleration = 15/1

= 15 m/s^2

Force = Mass × Acceleration

Force = 1000 kg × 15 m/s ^2

Force = 15000 N

<>>>>>>>>>>>>>>>>>>>>>

(iii) Distance = Area under graph

Distance = Area of trapezium

=> Area of trapezium = 1/2 × sum of parallel sides × Distance between them

=> Distance (s) = 1/2 ( BC + AD ) × (CF)

=> s = 1/2 × ( v + u ) × t

v = u + at

=> s = 1/2 ×( u + at + u ) × t

=> s = 1/2 × (2u + at) × t

=> s = 1/2 × 2ut × at^2

s = ut + 1/2 at ^2
