Answer:
The horizontal component of the force exerted by Marcie is 25 N
Explanation:
Lets explain how to solve the question
Marcie shovels snow after a storm by exerting a force of 32 N on her
shovel at an angle of 50 degrees to the vertical
We need to find the horizontal component of the force exerted by Marci
The force direction is 50° to the vertical means
→ tan(50) = , where x is the horizontal component
of the force and y is vertical component
→ tan(50) =
By comparing between the two expressions of tan(50)
→ The horizontal component is Fx = F sin(50)
→ The vertical component is Fy = F cos(50)
We need the horizontal component
→ F = 32 N
→ The horizontal component = 32 sin(50) = 24.51 N ≅ 25 N
