1.If a body moves in a straight line according to the law s= 24t +3t^2 - t³, where s is the distance measured in meters from the origin and t is the time in seconds after it starts to move, calculate the body’s velocity as a function of time.
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?
I think it's A but confused it might by C.
can you help me .
