Parabolic Motion, *throw a ball with velocity at angle 45 6.2m above ground

Click For Summary

Homework Help Overview

The discussion revolves around a problem in parabolic motion involving the trajectory of a ball thrown from a height of 6.2 meters with an initial velocity of 15 m/s at a 45-degree angle. Participants are exploring various aspects of projectile motion, including time of flight, horizontal range, maximum height, and impact conditions.

Discussion Character

  • Exploratory, Mathematical reasoning, Problem interpretation

Approaches and Questions Raised

  • Participants suggest developing equations related to uniform acceleration and kinematics to analyze the motion. There is mention of splitting the initial velocity into horizontal and vertical components to apply kinematic equations effectively.

Discussion Status

Several participants have provided guidance on using kinematic equations and suggested specific formulas for calculating the range and other parameters. The discussion is active, with multiple interpretations of the problem being explored, but no consensus has been reached on a specific approach.

Contextual Notes

Participants are working under the constraints of the problem as presented by the original poster, which includes specific values for initial velocity and height. There is an emphasis on using appropriate equations for projectile motion without providing complete solutions.

Jimmy tosses a ball with a velocity of 15m/s at 45degrees to the horizontal from a hill
6.2metres above ground.
Find:
-time of flight
-horizontal range
-maximum height
-speed of the ball when its 3m below the hill
-angle at which ball hits ground

Thx a lot, ANY help would be appreciated.

u should be able to develop a set of equations with your maths..
Umm... making use of uniform accelerated equations such as
v=u+at
s=(u+v)t/2
v^2-u^2 =2as
s=ut+1/2at^2
 
you could find range with R=1/16(Initial velocity)2sin(angle)cos(angle)

Split that into vertical and horizontal components(this is always constant).
Use the kinematics equations and consider vertical and horizontal motion.
