V = 1 - 9t if t<9
V= 5 - 2t if t =10
Find the value of v (m/s) when t = 5
-44 m/s
-34 m/s

V = 3 - 9t if t<5 ...(i)
V= 8 - 2t if t =10 ...(ii)
When t = 5,
V = 1 - 9(5) = -44 m/s
V= 5 - 2t if t >9
V = 3 + 9t if t<9
V= 8 - 2t if t =10
Find the value of v (m/s) when t = 10
V = 3 + 9t if t < 9
V = 8 -9t if t<1
V = 8 - 2t if t > 2
Find the value of V (m/s) when t = 3.
V = 1 - 4t if t<4
V= 5 - 2t if t >6
Find the value of v (m/s) when t = 7
