a.v = 30t – 3t²

b.v= 30t - t²

c.v = 24 + 3t- t^2

d.v = 24 +6t -3t²

I think it's D but also confused by A

2.what is the velocity of the body in question 10 when t = 3seconds?

a.15 m/s

b.27 m/s

c.63 m/s

d.81 n/s

I think it's A but confused it might by C.

can you help me .

2) v = 24 +6t -3t²

when t = 3

v = 24 +18 - 27

v = 15 or in other words a.
