Physics 1 Mechanics: Acceleration and Projectile Motion on a Ramp

Click For Summary

Discussion Overview

The discussion revolves around a physics problem involving the acceleration of a baseball on a ramp, focusing on projectile motion. Participants are tasked with calculating the launch velocity, the distance the ball travels, and the maximum height of a wall that the ball can clear after being launched.

Discussion Character

  • Homework-related
  • Mathematical reasoning

Main Points Raised

  • One participant presents the problem, specifying the parameters such as acceleration, ramp length, and angle.
  • Another participant requests guidance on how to approach the problem and where to post it correctly.
  • A third participant suggests a method to find the launch speed using the formula for kinetic energy, indicating that the acceleration and distance can be used to determine the speed at the end of the ramp.
  • There is a mention of using angles to calculate the distance the ball will travel and the time it remains airborne.

Areas of Agreement / Disagreement

Participants express uncertainty about the starting point of the problem and how to proceed, indicating that there is no consensus on the approach to take.

Contextual Notes

Some participants may be missing foundational assumptions or specific formulas needed to solve the problem, and there is a lack of clarity on the correct forum for posting such questions.

Who May Find This Useful

Students studying mechanics, particularly those interested in projectile motion and acceleration problems.

A baseball is accelerated from rest at the rate a = 251 m/s/s along a rising ramp of lenth l=3m. The ramp makes an angle of theta =.5 rad with the horizontal. Neglect friction.

a)what is the launch velocity v knot of the ball? express v knot in a component form using a coordinate system of your choice. Sketch the ramp and show v knot and your coordinate system.

b) how far down the range x from the launch point does the ball land?

c) suppose a wlal of heigh h stands at a distance d=x-31 m down range from the launch point. If the ball sails over the wall, waht is the maximum wall height?

How would you approach this problem? You are given acceleration in m/s^2 and length over which you accelerating, so you can find the speed at the end of the ramp now. Next you are given angles that gives you the distance that the ball will travel and stay airborne for. Just think about this problem, use appropriate formulas, and post if you get stuck

speed2 = 2*acceleration*distance
