math work

1.The acceleration of a particle is given by the equation: 

A = [a]*t.  If V = [e] m/s at t = 1 sec and S = 12 m at t = 1sec

Find S at t = 2 sec.

2.Find the area between the curves for the equations below and round your answer to one decimal place.

y = x2 + [b]x – 4 and y = x + [a]

a=3

e=2
