Find the dx for an object projected at 100 m/s from 20 degrees to 70 degrees in 5 degree intervals. How would you exactly do this? Would you use the equation Ay = A sin X?
Skotster said:break up your Vi=100m/s at 20 degrees into the x&y components
Vix=Vi*cos(20 degrees)
Viy=Vi*sin(20 degrees)
assuming you are on earth and ingoring air friction
use
Vf=Vi+(-9.8m/s^2)*t
to get
t=(Vf-Vi)/(-9.8m/s^2)
lettin Vf=0 to find time to max height
double it to get the total air time
use total time in
dx=Vix*t
