Projectile Motion - Initial Velocity

Click For Summary

Homework Help Overview

The discussion revolves around a projectile motion problem involving a motorbike jumping over a wall. The scenario includes specific measurements for the height of the wall and the ramp, as well as the distance from the ramp to the wall.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to analyze the problem by considering the horizontal and vertical components of motion, suggesting the use of uniform motion equations to determine the time taken and initial velocity. Participants also question the angle of the ramp and its relevance to the problem.

Discussion Status

The discussion is ongoing, with participants exploring different aspects of the problem, including the ramp's angle and its implications for the calculations. There is no explicit consensus yet, but various lines of reasoning are being examined.

Contextual Notes

The problem does not specify the angle of the ramp, which is a point of inquiry among participants. This missing information may affect the approach to solving the problem.

Good Afternoon, wondering if I could get some assistance. I'm not formally learning physics its just an interest I have, and try to complete problems during my spare time.

I have one particuar question that I'm stumped with, so any help would be great!

Q: You are asked by a film director to organise a stunt scene in which a motorbike mounts a ramp before safely jumping a wall. The wall is 4m high and the end of the ramp is 0.5m high and placed 10m back from the wall. What is the speed the stunt rider must drive off the ramp in order to jump the wall?

I understand that I need to split into horizontal and vertical components(?) then use uniform motion equation to get time taken and ultimately the initial velocity? Is this correct?

Kind regards

Steve

what is the angle of the ramp
 
it doesn't say, but would I be correct in saying that Tan<x>3.5/10?
 
Sorry, should have said...tanx=3.5/10.

As I say l, any help is appreciated
