Q1. You wish to put a 1000 kg satellite into a circular orbit 300 km above the earth’s surface. The earth’s radius and mass are RE= 6.38 × 106m and mE= 5.97 × 1024kg. (a)Find the force on the satellite applied by the earth.(b)What speed, period, and centripetal acceleration will it have?           

 Q2. A sinusoidal wave is traveling on a string with a speed of 40 cm/s. The displacement of the particles of the string at x = 10 cm varies with time according toy = (5.0 cm) sin[1.0 − (4.0 s−1)t] The linear density of the string is 4.0 g/cm.(a)What is the tension in the string?(b)What are the frequency and the wavelength of the wave? 

  Q3. A solid cylinder of radius 10 cm and mass 12 kg starts from rest and rolls without slipping a distance L = 6.0 m down a roof that is inclined at the angle θ = 30◦ as shown in Figure. The roof's edge is at height H = 5.0 m from the ground. The moment of inertia of a solid cylinder through the centerof mass is Icm = 1/2 MR2, where M and R are the mass and radius respectively of the solid cylinder. You can neglect the air friction for all calculations.(a) (What is the angular speed of the cylinder about its center as it leaves the roof? (b) At what velocity did the solid cylinder strike the ground?
