Projectile motion at an angle problem

Click For Summary
SUMMARY

The problem involves calculating the range of a projectile launched at a 40-degree angle with an initial velocity of 28 meters per second. The vertical component of the initial velocity (Vyo) is determined to be 18 m/s using the sine function, while the horizontal component (Vxo) is calculated as 21.4 m/s using the cosine function. The total time of flight can be derived from the equation Ttotal = (2Vyo)/g, where g is the acceleration due to gravity. The user seeks further guidance on completing the calculations for the distance traveled before the ball hits the ground.

PREREQUISITES
  • Understanding of projectile motion principles
  • Familiarity with trigonometric functions (sine, cosine)
  • Knowledge of kinematic equations
  • Basic understanding of gravity and its effects on motion
NEXT STEPS
  • Calculate the total time of flight using Ttotal = (2Vyo)/g
  • Determine the horizontal distance traveled using X = Vi*t + (1/2)At^2
  • Explore the effects of varying launch angles on projectile range
  • Review the concepts of maximum height and time of flight in projectile motion
USEFUL FOR

Students studying physics, particularly those focusing on kinematics and projectile motion, as well as educators seeking to clarify these concepts for their students.

Homework Statement


A ball is thrown at a 40 degree angle from the horizontal over level ground. If the initial velocity of the ball is 28 meters per second, how far does the ball travel before hitting the ground?

Homework Equations


X=Vi*t+(1/2)At^2
Ttotal=(2Vyo)/g
sine/cosine/tangent
A^2+B^2=C^2

The Attempt at a Solution


Vyo = 18m/s because Sin(40)*28
Vxo = 21.4m/s because Cos(40)*28

aaand I'm stuck. What do I need? Where do I go?
SO CONFUSED :P
