I'm not sure if it's due to their low mass and consequent lack of inertia or what, but very small insects are extremely resistant to injury through falling. What I'm wondering is, if we've got a tiny little bug diving toward the sidewalk at terminal velocity, would it still survive, or would it splatter?

A particle moves at a speed of 3.0m/s in the +x direction. Upon reaching the origin, the particle receives a continuous constant acceleration of 0.75m/s^2 in the -y direction. What is the position of the particle 4.0s later?
I also need the work arriving at the answer. Thanks so much!!

How can it be that photons can travel at the speed of light but objects that have mass cannot? Is it E=mc^2 wrong? I know that energy = mass and that mass = energy. But here it says the contrary when it is stated that photons don’t have mass.
