# Calculus: is it possible to find distance traveled with velocity and acceleration w/o antiderivative formulas?

I have a problem where I’m given the velocity (not linear). And I find the acceleration (not linear). With those how do you find the distance traveled (NOT displacement) without using antiderivative formulas (we haven’t gotten to that part yet)?

# If a galaxy has a recessional velocity of 5000 km/sec, what would be its distance?

Even if someone can give me a formula to help me find the distance that would be fantastic! I’m good at math but don’t even know where to begin with this

# Vectors: Finding the angle of a projectile when you have distance and velocity?

I won’t bore you with some word problem, instead I just want to know a way I can find the angle a projectile was shot at when all I have is the distance traveled in X and velocity. Please don’t use some advanced, higher level formula for it – stick with newbie ones. Thanks! (Ignore [...]

# What are the formulas for velocity, speed, distance, time & acceleration?

I need it for a quiz all at once. Thank you.

# You accelerate from rest for 3 seconds while traveling a distance of 100m. What is your final velocity?

You accelerate from rest for 3 seconds while traveling a distance of 100m. What is your final velocity? I was wondering if you use this formula v2=u2+2as?

# what is the effect on velocity if twice the distance is traveled in half the time?

explain your answer: WHOLE QUESTION IS: When velocity is constant, distance traveled, d, is given by the formula d=v*t, v is velocity, t is time. What is the effect on velocity if twice the distance is traveled in half the time? THANKS TO ANYONE WHO ANSWERS!

# Which formula do you use to calculate the final velocity after accelerating?

Which formula do you use to calculate the final velocity after accelerating? Which formula do you use to calculate the distance traveled when accelerating?

# what is the formula for constant velocity?

i need to know the formula a.s.a.p, as it is part of my holiday homework i heard the formula is constant velocity=distance/time i need to know if that is correct >.

# How to find velocity and distance of galaxy?

Light is gathered from a distant galaxy and one of the spectral lines of Calcium is observed at 413.26 nm when it should be 393.37 nm. (a) Find the velocity of this galaxy (hint: Doppler formula). (b) Find the distance to this galaxy (hint: Hubble Law). Can anyone help, please show work. Thanks!
