The velocity of a body A is given by v(t) = 2t^i + t

3^j. The body starts from rest at time t = 0 and

position s(0) = 2^i 10^j.

At what time, t, does the body cross the X axis?

What is the average velocity of the body for the time interval, t = 0 and the time that it crosses the

X axis?

What is the average acceleration of the body for the time interval, t = 0 and the time that it crosses

the X axis?
