Homework 1. A skg block, resting on a rough horizontal
surface is connected by a light in extensible
String over a light frictionless pulley to
second block of mass
mass 3kg hanging vertically.
An applied force of f is acting
the
block as shown in the diagram, and
the study coefficient Of kinetic frictia
between the sky and the surface is
Qa. The sto block accelerates to the
boot.
5 kg
a) Calculate the acceleration of the blooks.
b) Calculate the tension T.​

Four potential forces can act on the ball. which combination of forces will keep the ball in static equilibrium? the length of the arrows represents the magnitude of the force.

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
