<span>Transitional environments</span>
Because the speed of the sled is constant throughout this ordeal, we know that the instantaneous and average velocities are equal, and the velocity of the sled is
(negative because we're taking the downward direction to be negative)
The vertical component of this vector is given by
where is the angle made by the velocity vector with the positive -axis (taken to be the right direction). Here, , so
Im not quite sure but it might be a or c... ill double check
Answer:
hope it helps......
