A man is riding his motorcycle with a 3 m/s towards his head. He has a mass of 70 kg with supplies 300 watts of throttle during riding the motorcycle. The drag coefficient of 0.88 and area of the tires are 3.9 ft² =0.362 m², and the coefficient of friction is 0.007. Calculate the speed Vm of man in m/s at standard atmosphere.

A hydraulic press must be used to press-fit two components together in an assembly process. The system must generate at least 975 lb of force to perform the press fit. The piston at the input cylinder is pushed with a force of 250 lb and has an area of 30 in.2. The output can use up to 15 cylinders that are each 30 in.?. How many output cylinders must be incorporated into the design? Hint (you cannot have a fraction of a tangible item - i.e. you cannot have a decimal of a cylinder)
