Refer to the following information for the next five questions.

Scenario #1: A rock dropped from a 20 meter bridge falls into the river below.

Which kinematics variables are stated in this problem?

v_oinitial velocityv_ffinal velocitya
accelerations
displacementt
time interval

At what velocity does it strike the water?

Which kinematics equation did you use to solve this problem?

Based on the ORIGINAL givens, which equation would you now use to determine how much time it takes for the rock to reach the water?

How much time did the rock take to reach the water?

Refer to the following information for the next two questions.

Scenario #2: The rock is now tossed upwards at 6 m/sec from a 20 meter bridge falls into the river below.

At what velocity does it strike the water?

How much time did the rock take to reach the water?

Refer to the following information for the next two questions.

Scenario #3: The rock is now thrown downward at 6 m/sec from a 20 meter bridge falls into the river below.

At what velocity does it strike the water?

How much time did the rock take to reach the water?

Refer to the following information for the next five questions.

Scenario #4: A rock is thrown straight up into the air and returns to its original release position after 3 seconds.

Which kinematics variables are stated in this problem?

v_oinitial velocityv_ffinal velocitya
accelerations
displacementt
time interval

If you want to determine how fast the rock was released, which kinematics equation should you use?

How fast was it released?

Which equation(s) could you now use to determine how high it rose up into the air?

How high did it rise?
