For diffraction the wave length must be of the order of the opening.

The wavelength$?=\frac{h}{p}=\frac{h}{mv}$

Or$10m=6.63\cdot {10}^{-34}J\frac{s}{1400kg\cdot v}$

Or$v=4.7\cdot {10}^{-38}$ m/s

At a speed of 30m/s , calculate the wavelength?

If ? << than 10m there will be no diffraction.

If a tank holds 5000 gallons of water, which drains from the bttomof the tank in 40 minutes, then torricelli's Law gives the volume Vof water remaining in the tank after t minutes $(1-{\frac{t}{40}}^{2})5000=V0\le t\le 40$ .

Find the rate at which water is draining from the tank after (a) 5min, (b) 10 min. At what time is the water flowing out the fastest?the slowest?

A 2.0-kg projectile is fired with initial velocity components ${v}_{0x}=30$ m/s and ${v}_{0y}=40$ m/s from a point on the earth's surface. Neglect any effects due to air resistance. What is the kinetic energy of the projectile when it reaches the highest point in its trajectory? How much work was done in firing the projectile?

When a person stands on tiptoe (a strenuous position), the position of the foot is as shown in Figure (a). The total gravitational force on the body, vector F g, is supported by the force vector n exerted by the floor on the toes of one foot. A mechanical model of the situation is shown in Figure (b), where vector T is the force exerted by the Achilles tendon on the foot and vector R is the force exerted by the tibia on the foot. Find the values of vector T , vector R , and θ when vector F g = 805 N. (Do not assume that vector R is parallel to vector T .)

A rotational axis is directed perpendicular to the plane of asquare and is located as shown in the drawing. Two forces,1and 2,are applied to diagonally opposite corners, and act along the sidesof the square, first as shown in part a and then as shown inpart b of the drawing. In each case the net torque producedby the forces is zero. The square is one meter on a side, and themagnitude of 2 is5 times that of 1.Find the distances a and b that locate the axis. Notethat a and b are not drawn to scale.

a=___m

b=___m
