Question

answer the following
​

Answer 1

Answer:

a) Velocity at 5 seconds is 14m/s.

b) Acceleration = slope of velocity time graph = (14−2)(6−0)(14−2)(6−0) = 2 m/s2

c) Distance covered i.e. Total distance covered = area under ABCD = area of ABED + area of BCE = ((6-0)x(6-2)) +(14−6)×(6−2)2(14−6)×(6−2)2 = 24 + 16 = 40
