Question

A chair of mass 11.5 kg is sitting on the horizontal floor; the floor is not frictionless. You push on the chair with a force F = 42.0 N that is directed at an angle of 38.0 below the horizontal and the chair slides along the floor.

*Use Newton's laws to calculate the normal force that the floor exerts on the chair.

Answer 1

Answer:112.7 N

Explanation: mass of chair = 11.5kg, g= acceleration due to gravity = 9.8m/s^2

F = applied force = 42.0 N

The normal reaction is always acting upwards which is given as

R = mg = 11.5 × 9.8 = 112.7 N

Answer 2

Answer: Normal force = 139N
