1.45 is incorrect.

1.2. A car moves 200m at a 65° angle "north of east". It stays at rest for a while then moves 350 m at a 40° angle "south of west" Find the total displacement of the car.

Q1. a) In an adult, the aorta's radius is normally 1.5 cm and blood moves through it at the average velocity of 30 cm/s. If a typical capillary vein has a constant radius of 5 x10m and blood passes through them with a velocity of 0.1 cm/s, approximately how many capillaries are needed in a body? b) Benzene at 1 atm and 80°C enters the pipe system given in the below figure, with a Reynolds number of 130000 and leaves the system at 60°C. Assuming that diameters of the pipes at the exit are equal to each other, calculate the Reynolds number on one of the exit pipes (density of liquid benzene at 80° C= 813 kg/m' and at 60°C = 835 kg/m³). 3 in st 80 5 in st 80 3 in st 80

8:  The kinetic energy E of a body is proportional to its weight W and the square of its velocity v.  A 10 lb body moving at 6 ft/sec has an 8 ft – lb of kinetic energy.  How much is the kinetic energy of a 2 ton ( 4,000 lb ) truck speeding at 45 kph ( 66 ft/sec )?. Select one: a. 268,400 ft – lb b. 325,500 ft – lb c. 387,200 ft – lb      d.  258,900 ft - lb
