Explanation:
From the question we are told that:
Open cart of mass
Speed of cart
Mass of package
Speed of package at end of chute

a)
Generally the equation for work energy theory is mathematically given by
Therefore
The elephant and the mouse having zero weight in a gravity free space will not bump into you at the same effect.
<u>Explanation: </u>
When both are in a gravity free space, the weights are zero, as we know that the
But when they will acquire the speed of same magnitude, say v, their different masses will acquire different momentum, which will make the difference in effect while bumping.
And as we know Therefore, effect of impact by elephant will be more than that of mouse
. An elephant breaking into you will take you back faster than a mouse in space hits you.
