hey so I'm having a lot of trouble on this section of physics.
the question I'm on is:
Green light (546nm) strikes a single slit at normal incidence. what width slit will produce a central maximum that is 2.3 cm wide on a screen 1.42m from the slit?
I've been trying to manipulate...
In a grocery store, you push a 14.5 kg shopping cart with a force of 11.0 N. If the cart starts at rest, how far does it move in 3.00 s?
i've got that acceleration = force/mass
so the acceleration i got was .7586
but for some reason i keep getting the answer to the problem wrong...

HELP please: vector angles and velocity
Alright i don't nessesarily need an answer for this but maybe just a way to set it up. The problem is worded weird and no one can figure it out.
A passenger walks from one side of the ferry to the other side as it approaches a dock. If the...
I think this will be easy for someone who understands this stuff:
While riding on an elevato descending with a constant speed of 2.6 m/s you accidently drop a book from under your arm.
a. How long does it take for the book to reach the elevator floor, 1.1m below your arm?
(in seconds)...
