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 √(A^2+B^2+2ABcos\Theta)`

`\\ \tt\bull\leadsto √(8^2+2.5^2+2(8)(2.5)cos36)`

`\\ \tt\bull\leadsto √(64+6.25+40(0.8))`

`\\ \tt\bull\leadsto √(70.25+32)`

`\\ \tt\bull\leadsto √(102.25)`

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