UTS Senno

Soal A

import math

print('massa balok 1') a =eval(input()) print('massa balok 2') b =eval(input()) print('massa balok 3') c =eval(input()) print('massa balok 4') d =eval(input())

print( )

alfa=d/(a+b+c) print('maka didapat sinus alfa sebesar',alfa)

print( )

sudutalfa=math.degrees(math.asin(alfa)) print('Jadi besar sudut alfa adalah','/n',sudutalfa,'derajat')

Soal B

import numpy as np a = 5 b = 1 c = 2

def diff_v (t,v):

   fungsi = a - b -c
   return (fungsi)

v = 0 h = 1 step_size = np.arange (0,20,h)

for t in step_size:

   k1 = diff_v (t,v)
   k2 = diff_v ((t+0.5*h), (v+0.5*k1*h))
   k3 = diff_v ((t+0.5*h), (v+0.5*k2*h))
   k4 = diff_v ((t+h), (v+k1*h))

   v = v + 1/6*(k1+2*k2+2*k3+k4)*h

print ('maka v setelah 20 detik adalah', v)
