Question

Clarification:

1 h / 2 =

30 minutos

The whole statement is in the picture.

A block of mass ?1 = 250? is at rest on a plane that makes an angle ? = 30 ° about the horizontal. The coefficient of kinetic friction between the block and the plane is ?? = 0.100. This block is attached to a second block of mass ?2 = 200? that hangs freely from a rope that passes from a pulley without friction and with negligible mass. When the second block has fallen 30 cm, its speed is;

a). 83 cm / s

b). 160 cm / s

If the rope breaks, after having traveled h / 2, calculate:

The acceleration of each block.
The time block 2 reaches the ground.
The speed of block 2, an instant before it hits the ground and of block 1 when it reaches the end of the ramp.

3. A block of mass m1 = 250g is at rest on a plane that makes an angle 0 = 30 ° about the horizontal. The
coefficient of kinetic friction between the block and the plane is µc = 0.100. This block is attached to a
second block of mass m2 = 200g that hangs freely from a rope that passes from a pulley without friction
and with negligible mass. When the second block has fallen 30 cm, its speed is;
a, 83 cm /s
b. 160 cm / s
30
If the rope breaks, after having traveled h / 2, calculate:
• The acceleration of each block.
• The time block 2 reaches the ground.
• The speed of block 2, an instant before it hits the ground and of block 1 when it reaches the end of the
ramp.
