Mike (m = 40 kg) is riding his bike (m = 15 kg) at a velocity of +4.0 m/s. Mike decides to jump off his bike and achieves a new velocity of +5.0 m/s. Calculate the velocity of the bike after the collision.

Ahorizontal wire is tied to supports at each end and vibrates in its second-overtone standing wave. the tension in the wire is 5.00 n, and the node-to-node distance in the standing wave is 6.28 cm. (a) what is the length of the wire? (b) a point at an anti- node of the standing wave on the wire travels from its maximum upward displacement to its maximum downward displacement in 8.40 ms. what is the wire's mass?

What makes thermal imaging cameras useful? they can detect differences in color. they can detect differences in wave speeds. they can detect differences in temperature. they can detect mechanical waves.

Area around a charged object where the objects can exert a force on another charged objects is an electric
