  • Terminal velocity of two balls with different masses
    The discussion revolves around the terminal velocity of two balls with different masses falling through the Earth's atmosphere Participants explore the effects of mass and drag on acceleration and terminal velocity, considering both theoretical and experimental perspectives
  • Projectile: Find initial velocity without time - Physics Forums
    The discussion focuses on calculating the initial velocity (v0) of snow discharged at a 40-degree angle without knowing the time variable The solution involves using the equations for horizontal and vertical motion: L = v0 t cos (θ) and Δy = v0 t sin (θ) - (1 2) g t² By solving the first equation for time (t) and substituting it into the second equation, the initial velocity can be

    Calculate the velocity of the boat immediately after, assuming it was initially at rest The mass of the child is 24 0 kg and the mass of the boat is 35 0 kg FIGURE 7;31 Problem 7 (FIGURE CAN'T COPY) (II) A child in a boat throws a 5 30-kg package out horizontally with a speed of 10 0 m s, Fig 7-31
  • Angular Velocity Problem — a Piston and a Crank - Physics Forums
    The discussion revolves around a problem involving angular velocity in a mechanical system with a piston and crank mechanism Participants are addressing specific parts of the problem related to velocities and angular velocities at given angles, particularly focusing on the conditions when the velocity of point B is zero and when the angular velocity of link AB is maximized Participants are
  • How to find the initial velocity given only angle and distance traveled
    Right so vertically final velocity is zero We have the initial velocity as 27 586 m s at an angle of 33°, so what is the vertical component of this velocity? We have 1) Final velocity 2) Initial velocity 3)Acceleration and we want to find 4) distance Do you know a kinematic equation (SUVAT equations) that has all these quantities?
  • Does an Object in a Vacuum Accelerate Indefinitely?
    The discussion revolves around the behavior of objects in a vacuum, specifically addressing whether an object would continue to accelerate indefinitely without terminal velocity and the implications of symmetry in projectile motion, particularly concerning a bullet shot straight up and its return speed Some participants assert that in a vacuum, there is no terminal velocity, leading to the
  • Is there a difference between initial speed and initial velocity . . .
    The discussion revolves around the distinction between initial speed and initial velocity in the context of projectile motion The original poster presents a scenario involving a projectile launched at an angle, seeking clarification on whether the given speed can be considered as initial velocity Participants explore the definitions of speed and velocity, discussing the need for direction in
  • Relationship between Launch height and range of a projectile
    Participants discuss the factors influencing range, such as horizontal velocity and air time, while questioning the assumptions made about the effects of launch height Some suggest simplifying the explanation by comparing it to lowering the floor, while others provide insights into the equations governing projectile motion
  • Torque graph; finding angular velocity - Physics Forums
    The discussion revolves around interpreting a torque graph to determine the angular velocity of an object with a known moment of inertia The object starts from rest, and participants are exploring how to analyze the graph and apply relevant equations Exploratory, Conceptual clarification, Mathematical reasoning Participants discuss breaking the torque graph into segments to analyze angular
  • Angular acceleration, velocity, momentum of a door?
    The problem involves a door modeled as a uniform rod, focusing on its rotational motion around a vertical axis The scenario describes an external force applied by a person to slam the door shut, with various aspects of angular acceleration, velocity, momentum, and energy being explored Participants are tasked with analyzing the effects of different points of force application and the role of
