You are a bully. You pin a 48 kg dweeb to a wall so that his feet aren't touching the ground. Your arm is extended so that it makes an angle 28 degrees with the horizontal. The dweeb's back is so sweaty with fear that there is no friction between his back and the wall. What is the magnitude of the force , in N, you must apply to keep the dweeb in equilibrium? (Use g = 10 m/s2) This scenario is represented schematically below. Unfortunately for you, years later the dweeb is your boss and he makes your life miserable. (Please answer to the fourth decimal place - i.e 12.3445)
Let's consider the system given in Figure 2. The end of a flexible spring with spring constant k is attached to the wall and the other end to a block of mass m. There is no friction between the block and the inclined plane. When the spring is at its natural length, the block is first decelerated. The angle of inclination of the inclined plane is given as ß.
a) What is the acceleration of the blog when the spring is extended by x?
A block is set into motion up an inclined plane (30° ) with an initial speed of 8.0 m/s. There is friction between
the block ant the plane. The block comes to rest after traveling 4.8 m along the plane.
V% =8 m/s
What is the value of the coefficient of friction u?
HINT: remember that the friction force is given by
thus because both f and the N are proportional to the mass of the block m, m cancels out and you don't need it
to find u. Thus you wont be able to find a value for f or N alone, so find your acceleration first, then an
equation for µ that is independent of m.
