Yes but that will give me the instantaneous velocity of the jumper won't it? I think I'm trying to be too tricky with this problem

Homework Statement I'm plotting a man jumping over a car for maths and I'm trying to find the critical velocity at which the car has to travel for the jumper to make it safeley over the car the man's jump is approximated by the parabola y= -0.0176x^2 + 0.3595x - 0.2794 and restricted by the...

I was always taught that terminal zeroes are only significant if it is noted that they are significant (i.e 345000m six sig figs is completely different to 34500 3 sig figs) but yes as the others have stated, keep as many figures as you can until you reach the final answer and then round to the...

My dad loves being an engineer, he could travel wherever he wanted and get a job building things and not being chained to a desk, however he always tells me the one thing he hated was doing his thesis on concrete, he always joked that ke knew the properties of concrete more explicitly than...

Homework Statement So I'm determining the specific heat capacity of brass for a lab report, when i initially measured temperature it was to two significant figures (this was the measurement with the least significant figures) My final answer, remarkably was 0.38 (j/g*K) but my error was...

yeah thanks harrylin that's exactly what i was trying to figure out, much appreciated

Equation: M (ΔT)= The question: If ΔT has an error of one degree, and i multiply it by the mass of an object (m) is the error in y still one Attempted answer: or is it proportional to M i.e Δt plus or minus 1 degrees so the error in y is 2M? P.S i need to be able to know the error...
