Calculating Velocity when Stuntman Jumps from 1.25m Height

Click For Summary

Homework Help Overview

The discussion revolves around calculating the initial velocity of a stuntman who jumps from a height of 1.25 meters and lands 10 meters away. The problem involves concepts from kinematics and projectile motion, particularly focusing on the relationship between vertical and horizontal components of motion.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Participants explore the use of kinematic equations and question the assumptions about the horizontal jump. There is discussion about the distinction between average speed and initial velocity, as well as the implications of gravitational acceleration on the motion.

Discussion Status

The conversation is ongoing, with participants providing insights into the nature of horizontal and vertical components of velocity. Some participants suggest reconsidering the assumptions made about the jump's trajectory and the forces acting on the stuntman.

Contextual Notes

There is confusion regarding the application of gravitational force and the net forces acting in horizontal and vertical directions. Participants are also reflecting on the implications of using different components of motion in their calculations.

But, If I think of hypotenuse then, there is force
Yes there is force along the hypotenuse, there is a component of the gravitational force along that way. But we usually talk about this component when we have an inclined plane, here we have a different case, and as I told you before the trajectory of the cyclist is not along the hypotenuse.
