A child pulls a rope attached to a stone with the force of 16 Newton the Rope makes an angle of 40 degree to the ground 1. calculate the effective value of the pool tending to move the stone along the ground 2. calculate the force tending to shift this stone

The force is given and the angle of inclination is given.

The effective value of pull tending to move the stone along the ground being asked isthe component of the force applied along the x axis,therefore,

F = 60 cos 40°

= 60 x 0.766

= 45.96 N

F = 46 Newton
