A“flying pig” toy is suspended by a 0.50-m–long light string, and flaps its wings to travel in a clockwise circular path (as viewed from above). the string makes an angle of 30º with the toy’s vertical axis of rotation, and the pig has a mass of 2.0 kg. (a) what is the tension in the string? (b) what is the angular momentum of the pig about the vertical axis of rotation?

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?
