Question

NEED HELP !!!!!! READDD THE QUESTION THERE ARE TWO PARTS

Answer 1

We have to find horizontal component of Mayosons velocity.

#a

$\\ \tt\bull\leadsto V_x=vsin\theta$

$\\ \tt\bull\leadsto V_x=2.5sin36$

$\\ \tt\bull\leadsto V_x=2.5(0.58)$

$\\ \tt\bull\leadsto V_x=1.45m/s$

#b

Here 2 vectors A=8 and B=2.5

$\\ \tt\bull\leadsto \overrightarrow{R}$

$\\ \tt\bull\leadsto \sqrt{A^2+B^2+2ABcos\Theta}$

$\\ \tt\bull\leadsto \sqrt{8^2+2.5^2+2(8)(2.5)cos36}$

$\\ \tt\bull\leadsto \sqrt{64+6.25+40(0.8)}$

$\\ \tt\bull\leadsto \sqrt{70.25+32}$

$\\ \tt\bull\leadsto \sqrt{102.25}$

$\\ \tt\bull\leadsto 10.15m/s$
