    Projectile motion when you are only given time and range

    so then would it change to vy + (0.5*9.81*2.1^2)

    Projectile motion when you are only given time and range

    im confused now, how would that change the equation

    Projectile motion when you are only given time and range

    at half the time so 2.1 seconds?

    Projectile motion when you are only given time and range

    and the equation for height, would that be vy + (0.5*9.81*4.2^2) ?

    Projectile motion when you are only given time and range

    So if the horizontal displacement is 150 and the vx is 35.7 it would be 150/35.7=time=4.2 seconds?

    Projectile motion when you are only given time and range

    vix and time dictate horizontal displacement

    Projectile motion when you are only given time and range

    im sorry but i have no clue and I am not able to find it anywhere.
  8. A

    Projectile motion when you are only given time and range

    no acceleration in the x and a acceleration of -9.81 in the y?
  9. A

    Projectile motion when you are only given time and range

    for the x and y components of vi would it be 41.22cos30 and 41.22sin30?

    Projectile motion when you are only given time and range

    okay thanks and they don't contain either of those formulas and i don't see either in my notes as well.

    Projectile motion when you are only given time and range

    Homework Statement I am very lost and would love help. Given in the description is;"A golf ball leaves a golf club at an angel 30 degrees above the horizontal and lands on the green 150 meters away initial position." With this information i am supposed to find the balls initial velocity, how...
