Please Can Any Physicist Help Me Solve This Question by Nobody: 5:58pm On Nov 15, 2020
1.A 100kg satellite is in a circular orbit about the earth with a radius of 6.7x10^3km how much work would be required to raise the satellite to an orbit with a radius of 6.9x10^3km

2. A 15kg block is pulled by a donkey with a uniform speed along a rough horizontal surface with a force inclined at an angle of 45° to the horizontal. The coefficient of friction between the two the two surfaces is 0.3 if it covers 15m in 5minutes calculate;
i. The work done by the applied force
ii. The power generated
iii. Work done against the force of friction

Going through ur solving again I discovered that the value of G is supposed to be 6.7x10^-11 not 6.7x10^11
And please can you explain to me why the radius was halved while calculating distance. Sorry for bothering you sir

the distance to construct the circumference of the earth which is circular is twice the total radius.....d = r/2.....as for gravitation field constant i used u can use the appropraite value it was a mistake

A 15kg block is pulled by a donkey with a uniform speed along a horizontal surface with a force inclined at 45 to the horizontal.the coefficient of friction between the two surfaces is 0.3.if it covers 15m in 1hour 15 minutes 30sec, calculate the work done by the applied force, the power generated,the work done against the force of friction
