1 point In the absence of air resistance, a rock is thrown straight upward with an initial velocity of v_(0) . What is the velocity of the object at the instant it returns to the same height it was thrown from? Assume up is the +y +yaxis. vgt +v_(0) v=+v_(0) +v_(0)gt vgt 0 v=0 0lt vlt -v_(0) v=-v_(0) vlt -v_(0)

2 1 point Match the following properties to the average and Instantaneous velocities below. Not all terms will be used and each term only corresponds to one category. Note: both average velocity and instantaneous velocity will match with exactly two of the following properties. Average velocity Instantaneous velocity H derivative of displacement with respect to time 11 position divided by deltat Hisplacement divided by delta t Possible answers H derivative of distance with respect to time II distance divided by delta t 11 always equivalent to (v1+v2)/2 II constant for anyobject 11 between discrete times II at asingle "moment"
