so my local supermarket is doing a competition were you guess the amount of ducks in this trolley . [/B]
Its summer here in Ireland I have no college so I am pretty bored and said i would have a go at solving this with maths , but because its summer time it also means I am...
Just having a think about comets this morning .
Im guessing the tails associated with comets are fragments of rock and ice from the surface of the comets but
what is causing them to come off the surface if the comet is traveling through no medium to cause a force to move the bits that a make...
ummm
well the force by the distance will give me the work done
32 x 18 = 576J
Im almost sure there is a relationship between work and KE but i can't work out what ?:)
Homework Statement
An object is accelerated from rest by a force of 32 N over a distance of 18 m. Calculate the
kinetic energy of the object after 18 m

KE = 0.5 • m • v^2[/B]
The Attempt at a Solution
I can't work out where ill be able to get the mass or the velocity...
