TSny said:In these types of questions, you should interpret "the second it lands" as meaning "just before contact with the ground". So the duck is still in projectile motion at the time you are asked to find the velocity. The wording of the question was not very good.
Projectile motion is the motion of an object through the air under the influence of gravity. It follows a curved path known as a parabola, and is affected by the initial velocity, angle of launch, and acceleration due to gravity.
A rubber duck, like any other object, will follow the laws of projectile motion when thrown through the air. It will have an initial velocity and angle of launch, and will be affected by gravity as it travels through the air. The shape and weight distribution of the rubber duck may also affect its trajectory and landing.
The landing of a rubber duck can be affected by the initial velocity, angle of launch, acceleration due to gravity, air resistance, and any external forces acting on it. The shape and weight distribution of the rubber duck can also play a role in its landing.
Yes, the landing of a rubber duck can be calculated using the principles of projectile motion. By knowing the initial velocity, angle of launch, and other factors affecting its motion, it is possible to predict where the rubber duck will land.
Projectile motion is used in many real life situations, such as in sports like baseball or basketball, in fireworks displays, and in launching rockets and other objects into space. Understanding the principles of projectile motion can also help in designing and engineering structures and devices.
