Block A
is placed on a rough surface inclined at an angle θ
above the horizontal. A taut string connects block A
over a pulley to block B
, which hangs from the string, as shown below. The masses of blocks A
and B
are MA
and MB
, respectively. At time t=0
, block A
is sliding up the slope as block B
falls, and the blocks are both slowing down. Assume that the mass and friction of the pulley are negligible.

The gravitational force exerted on the block B is 20 N

The objective of this question is to determine the gravitational force exerted on block B.

From the diagram attached below, the free-body diagram shows that the gravitational force exerted on block B can be expressed as:

[tex]\mathbf{F_g = mass \times gravity}[/tex]

  • assuming that the mass on block B = 2 kg

∴

[tex]\mathbf{F_g =2 \ kg \times 9.8 m/s^2}[/tex]

[tex]\mathbf{F_g =19.6 \ kg.m/s^2}[/tex]

[tex]\mathbf{F_g \simeq 20 \ N}[/tex]

Therefore, we can conclude that the gravitational force exerted on the block B is 20 N
