Use the equation for the height of an object (in meters) at time t (in seconds) given below where so is the initial height and vo is the initial velocity. s(t) = so + vot 4.9t? An object is tossed into the air vertically from ground level and returns to Earth 9.9 seconds later. Determine the exact velocity at time t =3.9.

I've really been struggling with this one.
Expert Solution
Step 1
Given information:
The position from which the object is tossed(S0) = 0 m (ground)
The time it takes to return to the earth (t) = 9.9 sec
The time at which the velocity is required (t') = 3.9 sec
Given equation of motion:
The total displacement at the end is "Zero" i.e. when the body reaches back to ground. we can write this as:
