A re-supply satellite is launched from NASA/Wallops Island into a circular orbit of radius 6678 km with inclination of i = 38. In order to rendezvous with the ISS, the re-supply satellite needs to both raise it's altitude to 400 km, via a Hohmann transfer, and change the inclination to i = 51. Compute the delta-v for each maneuver and the total minimum delta-v for this set of maneuvers.
(Hint: order of maneuvers is important.)

A lap joint needs to be designed using 20-mm diameter bolts to carry a load of 120 kN on the connecting plates. If the shear stress in each rivet is not to exceed 90 MPa, determine the number of bolts needed.
The velocity of a particle along the s-axis is given by v = 17s^3/2 where s is in millimetres and v is in millimetres per second. Determine the acceleration when s is 3.3 millimetres.
