Two bodies of masses m1 and m2
are connected by a light string going
over a smooth light pulley at the end of an incline. The mass m1
lies on
the incline and m2
hangs vertically. The system is at rest; Find the angle
of incline and the force exerted by the incline on the body of mass m1
.

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called

Abike rider starts from rest and accelerates 28.0 meters down a slope in 5.00 seconds. what is her acceleration? select one: a. 3.21 m/sec2 b. 1.75 m/sec2 c. 9.80 m/sec2 d. 2.24 m/sec2

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) =_
