Achair of weight 95.0n lies atop a horizontal floor; the floor is not frictionless. you push on the chair with a force of f = 39.0n directed at an angle of 37.0 degrees below the horizontal and the chair slides along the floor.
1)using newton's laws, calculate n, the magnitude of the normal force that the floor exerts on the chair.

118.47

Explanation:

Given

force (F)= 39 N acting at an angle of 37 below horizontal

Force can be divided in to sin and cos component

Thus Fsin37 will act in Y direction

Total Force in Y direction is Normal reaction , Fsin37 and weight

N-mg-Fsin37=0

N=118.47 N

scorpions are,

c.arachnids

  scorpions are animals in the order scorpiones, under the class arachnida, which makes them a distant cousin of spiders
