g An object of mass 2.5 kg is executing the SHM attached to to a spring with spring constant 285.0 N/m. When the object is 25.0 cm from the equilibrium point it is moving with speed 0.60 m/s. Find amplitude of oscillations in cm.

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

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
