Answer:
Step-by-step explanation:
when s(t)=0
t^4-20t^2=0
t^2(t^2-20)=0
![t^{2} (t+2\sqrt{5} )(t-2\sqrt{5} )=0\\t=0,-2\sqrt{5} ,2\sqrt{5} \\so particle passes through origin when t=0,-2\sqrt{5} and 2\sqrt{5} \\\frac{x}{y} \frac{ds}{dt} =4t^3-40t\\when particle is motionless \frac{ds}{dt}=0\\4t^3-40t=0\\4t(t^2-10)=0\\t(t+\sqrt{10} )(t-\sqrt{10} )=0\\particle is motionless when t=0,-\sqrt{10} ~or~\sqrt{10}](https://tex.z-dn.net/?f=t%5E%7B2%7D%20%28t%2B2%5Csqrt%7B5%7D%20%29%28t-2%5Csqrt%7B5%7D%20%29%3D0%5C%5Ct%3D0%2C-2%5Csqrt%7B5%7D%20%2C2%5Csqrt%7B5%7D%20%5C%5Cso%20particle%20passes%20through%20origin%20when%20t%3D0%2C-2%5Csqrt%7B5%7D%20and%202%5Csqrt%7B5%7D%20%5C%5C%5Cfrac%7Bx%7D%7By%7D%20%5Cfrac%7Bds%7D%7Bdt%7D%20%3D4t%5E3-40t%5C%5Cwhen%20particle%20is%20motionless%20%5Cfrac%7Bds%7D%7Bdt%7D%3D0%5C%5C4t%5E3-40t%3D0%5C%5C4t%28t%5E2-10%29%3D0%5C%5Ct%28t%2B%5Csqrt%7B10%7D%20%29%28t-%5Csqrt%7B10%7D%20%29%3D0%5C%5Cparticle%20is%20motionless%20when%20t%3D0%2C-%5Csqrt%7B10%7D%20~or~%5Csqrt%7B10%7D)
