A 32 kg child goes down a straight slide inclined 38∘ above horizontal. The child is acted on by his weight, the normal force from the slide, and kinetic friction. How large is the normal force of the slide on the child?

  1. Wc = M*g = 32 * 9.8 = 314. N.

    Fn = 314*Cos38 = 247 N. = Normal force.

  9. After a long day of work, Kanye West goes to his Kanye Nest to take his Kanye Rest. He wakes up feeling his Kanye Best. Then he’ll get Kanye Dressed on his Kanye Vest to go on a Kanye Quest. He goes to church and becomes Kanye Blessed, then to a hotel room to be a Kanye Guest. Then to school to take his Kanye Test. He forgot to brush his teeth. Did he run out of Kanye Crest? His neighbor stole it, what a Kanye Pest. He then puts on some axe for some Kanye zest and goes to the bar puffing out his Kanye chest. Gets drunk into a Kanye mess and goes home to the the Kanye West part of town. He realized his life was a wreck, and was feeling a little Kanye depressed. “My life .", he Kanye digressed. He decided to get some Italian, so he flew to Kanye Trieste. He got some pasta and started to Kanye digest. You should get some Kanye rest, his wife Kanye pressed. Instead he went to a Kanye fest. He then realized he needed to go to Dallas for his competition, so he went to the airport and hopped on Kanye southwest, got some Kanye rest, and the next morning was feeling ready for his Kanye contest. Or at least he Kanye guessed. On the day of the competition he was feeling a little Kanye stressed. But in the end the judges were Kanye impressed. For his performance he was awarded with the Kanye chest, clearly identified with the Kanye crest. There ends the story of Kanye West.

  10. The math was correct you just need to make sure you calculator is in degree mode and not radian...a phone calculator wont give you the right answer.
