Given: mearth = 5.98 × 1024 kg rearth = 6.37 × 106 m a satellite of mass 884 kg is in a circular orbit at an altitude of 532 km above the earth’s surface. because of air friction, the satellite eventually is brought to the earth’s surface, it hits the earth with a velocity of 3 km/s. let the gravitational potential energy be zero at r = [infinity]. the universal gravitational constant g = 6.67259 × 10−11 n m2 /kg2 . what is the total energy of the satellite in orbit? answer in units of j pdf

what was the answer?

which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?  

answer

a 75kg dining table

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
