This is an example of an undamped forced oscillation where the phenomenon of beats occurs. find the solution of the initial value problem: x" + 7.84x = 2 cos(3), x(0) = x' (o) = 0 x(t) = graph the solution to confirm the phenomenon of beats. note that you may have to use a large window in order to see more than one beat. what is the length of each beat? length = ! would you be able to explain why the beats phenomenon occurs for this particular example?

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

A1,700kg car is being used to give a 1,400kg car a push start by exerting a force of 140n the impulse on the smaller car during the 30.0s of contact is +670kg*m/s. what is the impulse of the smaller car on the larger car? -814 kg*m/s 0kg *m/s -670kg*m/s -550kg*m/s
