A crate of mass \( m \) is going down a frictionless inclined plane. The plane is at angle \( \theta \) with respect to horizontal,
Given \( \mathrm{m}=1(\mathrm{~kg}), \theta=28 \) (deg), \( \mathrm{g}=9.81 \mathrm{~m} / \mathrm{s}^{\wedge} 2 \).
(1) Find the magnitude of the normal force that the plane exerts on the crate (in N )
\( \square \)
(2) Find the magnitude of the crate's acceleration (in \( \mathrm{m} / \mathrm{s}^{2} 2 \) )
\( \square \)
Give your answers as numbers in the regulfed units (do not type the unit in the answer box) with 3 significant figures Use dot (.) for decimal point, not commal)
