Someone please help i beg you :((((
ladessa [460]

Answer:

From Newton’s second Law

F = ma

a = Fm = 300 N /(30 kg + 10kg) =

300 N/(40 kg) = 7.5 m/s2

Note: Sled mass is added because person will accelerate along with it.

It seems that the questions is to be a physics subject

Thank you and please rate me as brainliest as it will help me to level up.

Not sure how I am supposed to arrive to an answer
ANEK [815]

Integrating both sides once gives

\dfrac{\mathrm d\mathbf r}{\mathrm dt}=2e^t\,\mathbf i+3e^{-t}\,\mathbf j+4e^{2t}\,\mathbf k+\mathbf c

where \mathbf c is an arbitrary constant vector. Use the initial condition to find its value:

\dfrac{\mathrm d\mathbf r}{\mathrm dt}(0)=-\mathbf i+7\,\mathbf j=(2+c_1)\,\mathbf i+(3+c_2)\,\mathbf j+(4+c_3)\,\mathbf k

\implies\mathbf c_1=-3\,\mathbf i+4\,\mathbf j-4\,\mathbf k

Integrate again:

\mathbf r(t)=2e^t\,\mathbf i-3e^{-t}\,\mathbf j+2e^{2t}\,\mathbf k+\mathbf c_1t+\mathbf c_2

where \mathbf c_2 is another arbitrary vector of constants. Use the other initial condition to determine its components:

\mathbf r(0)=6\,\mathbf i+\mathbf j+3\,\mathbf k=(2+c_1)\,\mathbf i+(-3+c_2)\,\mathbf j+(2+c_3)\,\mathbf k

\implies\mathbf c_2=4\,\mathbf i+4\,\mathbf j+\mathbf k

Then the particular solution to this ODE is

\boxed{\mathbf r(t)=(2e^t-3t+4)\,\mathbf i+(-3e^{-t}+4t+4)\,\mathbf j+(2e^{2t}-4t+1)\,\mathbf k}
