Question

$	heta=53^{\circ}$

$u=50m/s$

$u_{x}=u \cos 	heta \Rightarrow u_{x}=50 	imes \frac{3}{5}$

$u_{x}=30 \mathrm{m} / \mathrm{s}$

$u_{y}=u \s

$60\sqrt 2 $

Vedclass · Answer

$	heta=53^{\circ}$

$u=50m/s$

$u_{x}=u \cos 	heta \Rightarrow u_{x}=50 	imes \frac{3}{5}$

$u_{x}=30 \mathrm{m} / \mathrm{s}$

$u_{y}=u \sin 	heta \Rightarrow u_{y}50	imes \frac{4}{5}$

$u_{y}=40 \mathrm{m} / \mathrm{s}$

$S=w t+\frac{1}{2} a t^{2}$

$a_{x}=0$

$a_{y}=-g \Rightarrow-10 \mathrm{m} / \mathrm{s}^{2}$

$x ightarrow 30 	imes 2+\frac{1}{2} 	imes 0$

$x=60 \mathrm{m}$

$y=40 x^{2}-\frac{1}{2} x+0 	imes 4$

$y=80-20 \Rightarrow y=60 m$

$=\sqrt{(60)^{2}+(60)^{2}}$

$=60 \sqrt{2} \mathrm{m} / \mathrm{s}$
