Average acceleration in the different axes
![a_x=\dfrac{\Delta v_x}{\Delta t}\\\Rightarrow a_x=\dfrac{4-1}{2.5-2}\\\Rightarrow a_x=6\ \text{m/s}^2](https://tex.z-dn.net/?f=a_x%3D%5Cdfrac%7B%5CDelta%20v_x%7D%7B%5CDelta%20t%7D%5C%5C%5CRightarrow%20a_x%3D%5Cdfrac%7B4-1%7D%7B2.5-2%7D%5C%5C%5CRightarrow%20a_x%3D6%5C%20%5Ctext%7Bm%2Fs%7D%5E2)
![a_y=\dfrac{\Delta v_y}{\Delta t}\\\Rightarrow a_y=\dfrac{3-3}{2.5-2}\\\Rightarrow a_y=0\ \text{m/s}^2](https://tex.z-dn.net/?f=a_y%3D%5Cdfrac%7B%5CDelta%20v_y%7D%7B%5CDelta%20t%7D%5C%5C%5CRightarrow%20a_y%3D%5Cdfrac%7B3-3%7D%7B2.5-2%7D%5C%5C%5CRightarrow%20a_y%3D0%5C%20%5Ctext%7Bm%2Fs%7D%5E2)

and ![a_y=0\ \text{m/s}^2](https://tex.z-dn.net/?f=a_y%3D0%5C%20%5Ctext%7Bm%2Fs%7D%5E2)
The magnitude of acceleration
![a=\sqrt{a_x^2+a_y^2}\\\Rightarrow a=\sqrt{6^2+0^2}\\\Rightarrow a=6\ \text{m/s}^2](https://tex.z-dn.net/?f=a%3D%5Csqrt%7Ba_x%5E2%2Ba_y%5E2%7D%5C%5C%5CRightarrow%20a%3D%5Csqrt%7B6%5E2%2B0%5E2%7D%5C%5C%5CRightarrow%20a%3D6%5C%20%5Ctext%7Bm%2Fs%7D%5E2)
Direction
![\theta=\tan^{-1}\dfrac{a_y}{a_x}\\\Rightarrow \theta=\tan^{-1}\dfrac{0}{6}\\\Rightarrow \theta=0^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%3D%5Ctan%5E%7B-1%7D%5Cdfrac%7Ba_y%7D%7Ba_x%7D%5C%5C%5CRightarrow%20%5Ctheta%3D%5Ctan%5E%7B-1%7D%5Cdfrac%7B0%7D%7B6%7D%5C%5C%5CRightarrow%20%5Ctheta%3D0%5E%7B%5Ccirc%7D)

Explanation:
Answer:
2.0 m
Explanation:
Energy is conserved.
Initial KE = Final PE + Work done by friction
½ mv² = mgh + Fd
½ mv² = mgh + mgμd
½ v² = gh + gμd
½ v² − gh = gμd
d = (½ v² − gh) / (gμ)
d = (½ (7.5 m/s)² − (10 m/s²) (2.1 m)) / ((10 m/s²) (0.35))
d = 2.0 m
