hey danielakkerma after staring at the free body diagram for a while i finally came to the conclusion that gneill is absolutely right! and that this is very much like a projectile with an initial velocity which is influenced by an acceleration mimicking that of gravity. also since the angle at...

lol it sure got messy, but i understand most of it. the only questions i have are: with v_x do you mean velocity with respet to x, and what do you mean by {itex}

ok i believe gravity is in play here, attached is diagram i scanned

ok since I am given initial velocity and displacement which is the length of the plate (2cm) then how do i find the acceleration

ok i have a problem to work on in my new course, and i was wondering what i need to do to tackle it. the question is as follows: An electron is projected with an initial velocity Vo=10^7m/s into the uniform field between the parallel plates "E". the direction of the field is vertically...

ok so how do i set it up

A 11.0-g bullet is fired horizontally into a 108 g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring of constant 154 N/m. If the bullet-block system compresses the spring by a maximum of 76.0 cm, what was the velocity of the bullet at impact...

ok so how do i find the potential energy of the spring, is it mgh?

PEs=1/2kx2 PEs=1/2(655375n/m)(0.0162m) PEs=83.888 so what is next

energy? i am really confused, can you please give me a step by step thanks

Today's cars have elastic bumpers that are designed to compress and rebound without any physical damage at speeds below about 5 mi/h (8 km/h). The material of the bumpers behaves essentially as an ideal spring up to that point but permanently deforms beyond that. If the compression corresponding...
