Two masses, mi= 1 kg and m3= 5 kg, are connected by a rigid rod of negligible weight (see Fig). The system is
pivoted about point 0. The gravitational forces act in the
negative z direction.(a) Express the position vectors and
the forces on the masses in terms of unit vectors and
calculate the torque on the system. (b) What is the
angular acceleration of the system at the instant shown
in Fig?

answer; the correct answer is technician a; ///100%good luck

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

less than one you can't create energy

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
