This rocket started at rest on the luanch pad. At a certain point in the time, WATER with a mass of 2 kg was coming out of the rocket with velocity of -10 m/s. If the ROCKET has a mass of 5 kg, what is the velocity of the rocket?

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

Ameter stick is pivoted at the 0.50-m line. a 3.0-kg object is hung from the 0.15-m line. where should a 5.0-kg object be hung to achieve equilibrium (the meter stick oriented horizontal and motionless)?

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_
