An airplane flying horizontally at a constant speed of 350 km/h over level ground releases a bundle of food supplies. Ignore the effect of the air on the bundle.

a)What is the bundle’s initial vertical component of velocity? =0

b)What is the bundle’s initial horizontal component of velocity? =350

c) What is its horizontal component of velocity just before hitting the ground? =350

I got the answers, but how do I calculate them?

Thank you!!

Vo = (350km/h,0deg.).

a. Yo = ver. = 350sin(0) = 0.

b. Xo = hor. = 350cos(0) = 350km/h.

c. Xo = hor. = 350cos(0) = 350km/h.

To calculate the answers, you need to understand the basic principles of projectile motion.

a) The bundle is released from the airplane, so its initial vertical component of velocity is zero. This means that it is not moving up or down at the moment it is released.

b) The airplane is flying horizontally at a constant speed of 350 km/h. This means that the bundle has the same horizontal component of velocity. Therefore, the initial horizontal component of velocity is also 350 km/h.

c) The horizontal component of velocity remains constant throughout the motion, so it is still 350 km/h just before hitting the ground. This is because there are no horizontal forces acting on it and the effect of air resistance is ignored in this situation.

It is important to note that these calculations are based on the assumptions given in the question. In reality, there might be other factors to consider, such as air resistance, which can affect the motion of the bundle.

To calculate the bundle's initial and final velocities in the given scenario, you need to consider the concept of projectile motion.

a) The bundle's initial vertical component of velocity is zero because it is released horizontally. In other words, there is no initial upward or downward movement.

b) The bundle's initial horizontal component of velocity is equal to the speed of the airplane, which is given as 350 km/h. It remains constant because there are no external horizontal forces acting on it.

c) The bundle's horizontal component of velocity just before hitting the ground remains the same, i.e., 350 km/h. This is because there are no horizontal forces acting on the bundle that would change its velocity.

It's important to note that in this scenario, we are ignoring the effect of air on the bundle. If air resistance is considered, it may affect the bundle's motion.
