Question

A block with mass m=4.7 kg is on a frictionless incline surface (incline angle =44 degree). An external force of F is applied parallel to inclined surface. If the block moves with a constant speed upward, find the magnitude of the applied force. Take g=9.81 m/s²and round your answer to 1 decimal place.

Answer 1

Let the magnitude of the applied force is F.

The mass of the block is m=4.7 kg.

The value of g=9.81 m/s2.

The block moves with a constant speed that means the net force along with the incline acting on the block are zero.

  

  

The magnitude of the applied force is 32.0 N.
