Q6. A block of mass 1 kg is placed on a truck which accelerates with acceleration 5 m/s. The coefficient of static friction between the block and truck is 0.6. The frictional force acting on the block is: C) 5.88 ND) 4.6 N E) None
4. A bucket with mass m2 = 5 kg and a block with mass mi-15 kg are hung on system. Find the magnitude of the acceleration with which the bucket and the block are moving and the magnitude of the tension force T by which the rope is stressed more masses of the pulley system and the rope. The bucket moves up and the blocsma down. Show all your work, and use as and as for the acceleration of the...
A block (block 5) of mass m5 = 2.3 kg hangs from the end of a (massless) string which runs over a (massless frictionless) pulley. The other end of the string is connected to another block (block 4) of mass m4 = 6.1 kg on a surface inclined at an angle of θ = 27o above the horizontal. The situation is shown below. a) Assuming there is no friction between block 4 and the inclined plane, find the acceleration (magnitude...
Block A has a mass of 2.87 kg and block B has mass 1.98 kg.
Block B is at the height ℎ = 1.50 m when the blocks are released
from rest. Determine the speed of block B just before it bumps into
the ground:
(a) if block A slides frictionlessly along its horizontal
planet; and
(b) if the sliding friction number between block A and the
ground is 0.18.
(Assume that the string and pulley have negligible masses and...
