The blocks are forced together, compressing a spring S be- tween them; then the system is released from rest on a level, frictionless surface. The spring, which has negligible mass, is not fastened to either block and drops to the surface after it has expanded. Block B acquires a speed of 1.20 m/s. (a) What is the final speed of block A?

A vehicle manufacturer is considering an engine for a new sedan (CD = 0.34, Af = 22 ft2). The car is being designed to achieve a top speed of 100 mi/h on a paved surface at sea level (ρ = 0.002378 slugs/ft3) and a grade of 2%. The car currently weighs 2000 lb, but the designers initially selected an underpowered engine because they did not account for aerodynamic, grade, and rolling resistances. If 2 lb of additional vehicle weight is added for each unit of horsepower needed to overcome the neglected resistance, what will be the final weight of the car if it is to achieve the 100-mi/h top speed? What is the maximum initial acceleration this car can achieve from rest on this particular road?

A double-acting cylinder has a plunger of 10 cm in diameter. The diameter ratio between the plunger and the stem is 5. This cylinder is connected to a compressed air network at the pressure of 2 MPa and performs 15 cycles per minute. Assuming a friction force equal to 10% of the theoretical one, calculate: a) The force exerted by the stem in the advance race and the one exerted in the return race. b) The stroke length if the air flow, measured under normal conditions, is 583 l/min. c) What would be the section of a single-acting cylinder, working with traction, that would provide the same flow?
When rowing downstream consider the following scenario. The current of the water is moving at 2 m/s in the direction you are rowing. The coefficient of drag between your boat and the water is 1.2, the area in contact with the water is 0.1 m2 and the density of the water is 1000 kg/m3. You are moving at a velocity of 4 m/s into a head wind of 4 m/s. Your coefficient of drag between you and the air is 1.4, the area in contact with the air is 0.4 m2 and the density of the air is 1.2 kg/m3. Your goal is to create a net force moving downstream that is equal to 100 N. How much force must you exert with the oar and in what direction to achieve this net force downstream?
A pipe of 50 mm diameter and 4,5 km length connects two reservoirs whose constant difference of water level is 12 m. A branch pipe 1,25 km long and taken from a point distance of 1,5 km from reservoir A, which leads to reservoir C whose water level is 15 m below that of reservoir A. Find the diameter of the branch pipe so that the flow into both the reservoirs is the same. Assume the coefficient of friction for each pipe, f=0.0075,and neglect minor losses.

A jet of water from a nozzle is deflected through an angle θ = 60° from its original direction by a curved vane which it enters tangentially (see Fig. 5.5) without shock with a mean velocity C1 of 30 m s−1 and leaves with a mean velocity C2 of 25 m s−1. If the discharge A from the nozzle is 0.8 kg s−1, calculate the magnitude and direction of the resultant force on the vane if the vane is stationary.
