##### Reference no: EM13541759

Two blocks are connected by a string over a frictionless, massless pulley such that one is resting on an inclined plane of 60 degrees and the other is hanging over the top edge of the plane. the hanging block has a mass of 400kg and the one on the plane has a mass of 200 kg. the coefficient of kinetic friction between the block and the inclined plane is 0.45 static is 0.5. the blocks are released from rest.

a. what is the value of static friction?

b. what is the value of kinetic friction?

c. will the blocks move? d> if so what is the aceliration?

#### Find what are the velocities of the balls after collision

A 4.0-kg ball with a velocity of 4.0m/s in the +x-direction collides head on elastically with a stationary 2.0-kg ball. What are the velocities of the balls after the collis

#### Determine how fast must the bucket move

A bucket of mass 2.00 kilogram is whirled in a vertical circle of radius 1.10 meter. Determine how fast must the bucket move at the top of the circle so that the rope does not

#### Calculate what is the angular speed of the rod

A uniform rod (L= 3 m) and mass (M = 1 kg) is pivoted about a horizontal frictionless pin through one end. What is the angular speed of the rod when it passes through the vert

#### Change in resistivity of platinum with temperature
