A 55-kg child sits on a 1.1-m radius playground merry-go-round without holding on to the rails. a. Someone pushes tangentially, resulting in a torque of 356 N m. How fast is the merry-go round moving (in m/s)?

if you answer my question i will answer yours

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
