larr Kopyas$-$ NEWTON'S SECO...

Answer the following in terms of M$1,$ M$2$ and g $($you can ignore friction$)$

$($a$)$ what is the total mass of the system, Msystem

$($b$)$ what is the force acting on M$1$ causing the acceleration?

$($c$)$ write an expression for the acceleration of the system in terms using Newton's Second Law in the form: $a=$ Fnet$/$Msystem $($in terms of M$1,$ M$2$ and g only$)$

If the mass is transferred from the cart to the hanging mass $-$how will each of the following change $($increase$,$ decrease or stay the same$)?$

$($a$)$ the total mass of the system

$($b$)$ the net force acting on the system

$($c$)$ the acceleration of the cart

$($d$)$ the acceleration of the hanging mass

Try an example $-$

Given $M1=0\mathrm{.}1kg$ and $M2=0\mathrm{.}5kg.$ Ignore friction

$($a$)$ Determine the total mass of the system

$($b$)$ Calculate the net force pulling on M$1($this would be the sum of the vectors W $1$ and T where W$1$ is the weight of M$1$ and T is the tension on the string$)$

$($c$)$ Calculate the net force Fnet on the system

$($d$)$ Calculate the acceleration of the system

$($e$)$ Calculate the force of the string $($tension$),$ T$,$ acting on M$2$
