If A= [1 2 5 4 1]
[6 1 3 7], then the
[2 3 2 9]
order of A is
A. 2 x 3
B. 3x2
c.3 x4 d. 4x3​

Acatapult is tested by roman legionnaires. they tabulate the results in a papyrus and 2000 years later the archaeological team reads (distances translated into modern units): range = 0.4 km; angle of launch = π/5 rad; landing height = launch height. what is the initial velocity of launch of the boulders if air resistance is negligible?

Identical marbles are released from the same height on each of the following four frictionless ramps . compare the speed of the marbles at the end of each ramp. explain your reasoning

Spend time observing or thinking about events that involve matter and energy. which events can you explain? which events can’t you explain?
