In an experiment to measure the speed of a bullet, the bullet is fired into a piece of plasticine suspended from a rigid support by a light thread. 24 cm bullet speed V plasticine The speed of the bullet on impact with the plasticine is V. As a result of the impact, the bullet embeds itself in the plasticine and the plasticine is displaced vertically through a height of 24 cm. The mass of the bullet is 5.2x10 kg and the mass of the plasticine is 0.38 kg. i. Ignoring the mass of the bullet, calculate the speed of the plasticine immediately after the impact. [2] ii. Deduce that the speed V with which the bullet strikes the plasticine is about 160 ms. [2]

A windmill turns a series of slender rods fixed about one end . They are initially 2 meters long, and go at a speed of 15 revolutions per minute. I suggested making the blades 1m long to reduce the cross-sectional area of the windmill, keeping the mass the same for mechanical stress consistency. How fast are the windmill blades going now, in revolutions per minute?

Please include explanation. A 6-MW offshore wind turbine has a capacity factor of 40%. It has a height of 120 m, and 107-m long blades. The angular acceleration is 1.388 rad/s2. Assume that the distance from the center of the turbine to the connection with the blade is negligible, and that the turbine starts from rest. At ? = 12 s, calculate the velocity and the acceleration for points (a) at half the length and (b) at the tip of the blade.

Two concentric cylinders are rotating in opposite directions but the same speed, 25 revolutions per minute. The outer cylinder, 11cm in diameter, is turning counterclockwise and the inner cylinder, 10 cm in diameter, is turning clockwise. The gap between the cylinders is filled with a liquid. The liquid is a Newtonian fluid with a viscosity of 0.1 kg/m.s. Both cylinders are 50 cm long. Assuming linear distribution of velocity in the gap, Sketch the velocity profile inside the liquid in the gap At what radial distance from the center of the cylinders the liquid velocity becomes zero?

In humans, blood flows from the heart into aorta, from which it passes into major arteries These branch into the small arteries (arterioles), which in turn branch into myriads of tiny capillaries. The blood returns to the heart via the veins. The radius of the aorta is about 1.2 cm, and the blood passing through it has a speed of about 40 cm / s. A typical capillary has a radius of about 0.0004 cm, and blood flows through it at a speed of about 0.05 cm / s. Estimate the number of capillaries that are in the body
