Answer:
C. 3 1/20
Step-by-step explanation:
3.05 as a fraction = 3 1/20
Therefore the answer is C.
Answer:
Thus we find that velocity vector at time t is
(5t+15, 5t^2/2, 4t^2)
Step-by-step explanation:
given that acceleration vector is a funciton of time and at time t

v(t) can be obtained by integrating a(t)
v(t) = 
Thus we use the fact that acceleration is derivative of velocity and velocity is antiderivative of acceleration.
The arbitary constant normally used for integration C is here C vector = initial velocity (u0,v0,w0)
Position vector can be obtained by integrating v(t)
Thus we find that velocity vector at time t is
(5t+15, 5t^2/2, 4t^2)
1/2 is one half---Erin
6/8=3/4----Laurn
Lauran scored mor goals because she scored 3/4 which is more than 1/2
