Write suitable functions of p and q which could be plotted against each other so as to obtain a straight line graph in the following cases.q= ap^n, q^m = ap^n, q= ab^p, q2=a(p2-b2)/p and q= AP+b+p2
a) Find the vector projection of F1B about
F1F2
b) Find the orthogonal projection of F1B about F1F2 and sketch the ellipse together with the obtained vectors.
If a boy lifts a mass of 6kg to a height of 10m and travels horizontally with a constant velocity of 4.2m/s, calculate the work done? Explain your answer.
7. What is the gravitational field strength at a distance of 60.0 km above the surface of the Earth?
3. A 27.0 kg object is being pulled east across the ground with a horizontal force of 110 N. If the acceleration of the box is 2.82 m/s ^ 2 , what is the coefficient of kinetic friction? (Ensure you draw a free body diagram.)
7. A student runs at 4.5 m/s [27 degrees S of W] for 3.0 minutes and then he turns and runs at 3.5 m\%; (35^ S of E[ for 4.1 minutes.
