    Answer:

    a) 4 √8m/s b) 40 m/s c) 16m d) 9m e) 16m f) 15s

    Step-by-step explanation:

    Given a= 2m/s^2 , u=0

    a) Given S=20

    By the formula

    v^2 =u^2 + 2as

    v^2= 0 + 2 (2)(20)

    v^2= 80

    v=4√8 m/s

    b)Given t=20s

    v=u + at

    v=0 + (2)(20)

    v= 40 m/s

    c) Given t=4s

    s=ut + 1/2 at^2

    s= 0 + 1/2 (2)(4)^2

    s= 16 m

    d) Given t=3s

    s=ut + 1/2 at^2

    s= 0 + 1/2 (2)(3)^2

    s= 9m

    e) Given t=4

    s=ut + 1/2 at^2

    s= 0 + 1/2 )(2)(4) ^2

    s= 16m

    f) Given S=25 m

    s=ut + 1/2 at^2

    25=0 + 1/2 (2) t^2

    t^2 = 25

    t = 5s

    Hope it helps!!
