(b) Find the wavelength of the electron.

1. A toy moves with constant speed around a circle. The radius of the circle R=3 m. When the toy is at point A, its velocity is 6 m/s î. When it is at point B, what is its acceleration (vector)?

2. Block A of mass mA =2 kg is on block B of mass mB =5 kg. The lower block is on a frictionless surface while the coefficient of static friction μs =0.25 between the two blocks. If they are moving together at constant velocity, v=5 m/s, what is the frictional force between A and B?

3. A particle starts from rest (v = 0) at time t = 0 and moves along the x axis. If the net force on it is proportional to t, its kinetic energy will be proportional to tn. What is the value of n?

4. A thin rod of length a varies in its composition in such a manner that its linear mass density is λ(x) = cx, where x is the distance from one end. Locate the position of center of mass (CM) relative to x=0.

5. Two blocks of masses m and 2m are held against a massless compressed spring within a box of mass 3m and length 4L whose center is at x=0. All surfaces are frictionless. After the blocks are released, they are each at a distance L from the ends of the box when they lose contact with the spring. Both blocks keeps moving until they collide with the box and stick to it. Find the distance of the center of the box moves from x=0 after both blocks stick to the box.

6. A lawn roller is a solid cylinder of mass M, radius R, and rotational inertia I=MR²/2. It is pulled at its center by a horizontal force of magnitude F and rolls without slipping on a horizontal surface. Find the acceleration of the cylinder.

7. A block of mass m is attached to a vertical spring via a string that hangs over a pulley of mass M and radius R. The rotational inertia of the pulley I=MR²/2. The string does not slip. Find the angular frequency (ω) of the simple harmonic motion.

8. The wave function of a wave is: y(x, t) = 0.3sin(0.4x + 40t + 0.6) where x and y are in centimeters (cm) and t is in second (s). Find the wave velocity.
