    A bomb is released from an airplane flying horizontally at an elevation 1600 ft with a velocity of 294 ft/s.

    I dont know how to get the magnitude. Will you please help me?

    The magnitude of its velocity just before striking

    This is a HW type problem. I have moved it to the Introductory Physics HW forum.

    You should state the appropriate formulas for solving this problem and show an attempt at a solution.

    What do you know about projectile motion?

    We only tackled this lesson yesterday and i only remembered that this is of course a straight line motion with two kinds of motion: vertical and horizontal. The formulas for vertical are: Vy=gt, h=1/2 g(t)squared and t=Vy/g. And for horizontal are: Vi=Vx and r=Vxt.

    My question a while ago is my teacher's first example so i dont have any idea of what i will going to use even he already taught the formulas.

    Maybe that the formula for the magnitude will be derived from the main formulas but i dont know where's the magnitude in that formulas

    You've got to calculate the vertical and horizontal velocities of the bomb when it strikes the ground before you can worry about the magnitude of anything. ;)

    You have to be well versed with vector. I advise you learn as much about vector as to solve problem as this and others involving displacement, velocity, acceleration and others.

    How do you find the magnitude of a vector, in general, when you know the x and y components?
