A cylinder of length L=0.4m and a mass M=2kg has one end pinned to the surface, in a frictionless environment. When another point mass, of m=0.1kg and velocity 5 m/s, hits it right at the end the point mass sticks to the cylinder and they both rotate around the pin. a.) What is the final angular velocity after the collision? b.) What is the linear velocity of the point mass stuck on the end of the the cylinder?

Sam is trying to move a dresser of mass m and dimensions of length L and height H by pushing it with a horizontal force F⃗ applied at a height h above the floor. (Figure 1) The coefficient of kinetic friction between the dresser and the floor is μk and g is the magnitude of the acceleration due to gravity. The ground exerts upward normal forces of magnitudes NP and NQ at the two ends of the dresser. Note that...

The length l, width w, and height h of a box change with time. At a certain instant the dimensions are l = 5 m and w = h = 2 m, and l and w are increasing at arate of 3 m/s while h is decreasing at a rate of 4 m/s. At that instant find the rates at which the following quantities are changing.Find Volume.__________ m^3/sFind Surface Area.__________m^2/sFind length of the diagnol.(find answer to two decimal places)__________m/s

a box with a mass of m = 3.25 kg on a surface inclined at an angle of 35.0°. The coefficient of static friction between the box and the surface is 0.330. Find the minimum magnitude of the force F (in N), applied to the box in a direction perpendicular to the surface, that will prevent the box from sliding down the surface.

4. In the figure shown, rod AB (M-2 kg, L-2 m, center of mass C located 1 m above ground) is kept on a rough surface (H-0.5). A horizontal force F = 10 N is applied to the rod at point D, and distance CD-L/3 m. This horizontal force F causes the rod to rotate about B. Find initial linear acceleration of the top-most point A of the rod. Figure inset shows moment of inertia of a rod. Ignore air...

m d[m] Problem 1 [20 points) A box of mass m = 6 kg slides down an inclined ramp of length d = 2 m as shown in the Figure. The box starts with initial speed 2 m/s at height h = 1 m from the bottom of the ramp. A constant friction force f = 3 N is applied to the box when sliding h[m] down the ramp. Consider the box of mass m, as your system. a) [5...

1. A box of mass M and height H with an open top of area A slides across a frictionless, icy surface of a frozen lake with a velocity V. It then starts raining. Assuming that the rain falls vertically with a speed w, the average raindrop has a diameter d, and n raindrops fall into the box per second, find the speed of the box as a function of time. If the rain continues to fall and doesn’t hit...
