Question-

What horizontal force should be applied to a large block of mass M shown in the figure above thus that the tan blocks remain stationary relative to M? Suppose all surfaces and the pulleys are frictionless. Notice that the force wielded by the string accelerates m2. (Utilize the following as necessary: m1, m2, M, and g.)
F =

Question-

A light rope passes over a light and frictionless pulley. One end is fastened to a bunch of bananas of mass M, as well as a monkey of mass M clings to the other end. The monkey climbs the rope in an effort to reach the bananas.

(a) Treating the system as consisting of the monkey, bananas, pulley, and rope evaluate the net torque about the pulley axis.

(b) Using the results of (a), decide the total angular momentum about the pulley axis and explain the motion of the system. Will the monkey arrive at the bananas?

Question-

A bicycle has wheels with a 30-cm radius. If smaller wheels with a 25-cm radius are installed and what is the change in linear speed of the bicycle if the wheels rotate at 1 revolution per second?

Question-

Three objects are connected on an inclined table as shown in the drawing below. The objects have masses 8.0 kg, 4.0 kg and 2.0 kg as shown and the pulleys are frictionless. The tabletop is rough with a coefficient of kinetic friction of 0.47 and creates an angle of 20.0° with the horizontal.
Draw a free-body drawing for each object.
Decide the acceleration and direction of motion of the system.
Decide the tensions in the two cords.

Question-

(b) How many measurements would have to be averaged to increase SIN to 10"

Question-

How much potential energy does she gain? it is being pulled by a spring balance produce 1metre per second squre...what is the reading on the spring balance?

Question-

A Venturi meter is a device for measuring the speed of a fluid within a pipe. The diagram shows a gas flowing at speed v2 during a horizontal section of pipe whose cross-sectional area is A2 = 0.0554 m2. The gas has a density of ρ = 1.30 kg/m3. The Venturi meter has a cross-sectional area of A1 = 0.0126 m2 and has been alternative for a section of the larger pipe. The pressure dissimilarity among the two sections is P2 - P1 = 97.2 Pa. Find (a) the speed v2 of the gas in the larger original pipe and (b) the volume flow rate Q of the gas.
