In summary, "should be simple problems" are tasks that initially seem easy to solve but may have underlying complexities. They are important for scientific research as they can reveal hidden insights and help scientists understand systems or processes. Scientists can identify these problems by critically examining the task and seeking input from other experts. Common challenges in solving "should be simple problems" include unexpected variables, unreliable data, and cognitive biases. To effectively approach and solve these problems, scientists can break them down, collaborate with others, and consider multiple perspectives.

Homework Statement



A 22.0 kg child slides down a slide that makes a 37.0° angle with the horizontal. What is the magnitude of the normal force that the slide exerts on the child?

Homework Equations



Fnormal= mg cos (x)


The Attempt at a Solution



Fnormal= 22.0kg(-9.80m/s^2) (cos 37)= 172N...but that's not right

I'm so confused..thanks for helping

ah, I see I didn't read the question carefully enough @_@ I put -172N for the answer instead of 172. Thanks!
