Normal force, acceleration and tension

Click For Summary
SUMMARY

The discussion focuses on calculating the normal force and acceleration of a 72 N block being pulled across the floor with a tension force at an angle of 33 degrees. The coefficient of kinetic friction between the block and the floor is 0.32. The normal force is determined by the equation N = mg - T*sin(θ), where T is the tension and θ is the angle of tension. The frictional force, which opposes the motion, is calculated using the normal force and the coefficient of friction.

Welcome to PF.

Generally the normal force is going to be m*g.

The Tension is apparently upwards which means that the upward component the tension T*Sinθ is pulling up and reducing the m*g

Whatever your normal force times the coefficient of friction is it will retard the forward pull of the Tension, which is the horizontal component of T.
