Which equation can be used to model simple harmonic motion? a. d=acos[w(t+k)] b. d=acos(wt) c. d=asin(wt)+k d. d=sin(awt)

Correct option is B.

Step-by-step explanation:

Given some equations we have to choose the equation which can be used to model simple harmonic motion.

The basic equation for simple harmonic motion are

x = acos(wt)  and x=asin(wt)

where x is displacement from resting position,  

a is the amplitude, which is the largest displacement the object experienced, w is the angular velocity or angular frequency and t is the time.

From the given options B option matches i.e

d=acos(wt)

is the equation can be used to model simple harmonic motion.

So, correct option is B.

i used to know but i learned it a long time ago sorry

step-by-step explanation:

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
